Wait until the first revision comes up! as always, the desperates install the new OS that come full of bugs and then complains starts "I lost all my data".
Just my 2cents.
Not to mention that this sort of upgrades just make you buying a new machine to run the system as it should.
Words of wisdom. Until Lion has been used widely, I'll sit it out for the first or second update.

Can't you also get them from AT&T? Also, the Apple Store in Santa Monica never has a line for new iPhones or iPads for some reason. I guess they work fast?

Apple support has been very average for me in Australia. I have 2 macbooks being repaired now, they both have multiple problems and have been at the repair place for over a week. I tried to get apple to just replace them but after being fowarded through several departments they told me no. When i have used dell support, I ring up and tell them what the problem is and someone comes to my house to fix the computer the next day. I thought apple was supposed to be better at support than dell?

To be fair, every smartphone on the market is an iPhone clone and every tablet an iPad clone, so it is all related to Apple in that way.
Complete BS "iphone" lookalikes date back to ebfore the iphone was anounced. So either some companys have people who can predict the future, or the design and tech behind the iphone was aused BEFORe it was released and apple just changed excisting designs.

The screen is not 50% smaller. Nice way of making yourself look stupid.
What BaldiMac said. The 3" increase in screen size of the iPad more than doubles the screen's dimensions.

Too many people are complaining about rumored information that isn't even reliable, and most likely incorrect.
I think we can look at what Apple has done with its other lineups this past year as a guide to the future. Based on what we've seen, I don't think Apple will be redesigning the Mac Pro case -- it's large enough to accommodate anything they wish to throw in there. I also think it's a great industrial design, physically alluding to the power within.
The one question I do have is why is the Mac Pro the last to make this transition, why has it taken so long? Is it simply due to chip availability, is it due to some radical new design, or is it because the Mac Pro is Apple's flagship product and Apple is working long and hard to wedge in some great new technology?
Great new technologies always made their way to the Power Macs first, and then trickled down the line. I have every faith that the Mac Pro will continue this tradition, especially since the Mac Pro will be competing with other high-end Xeon workstations. Apple will need something in the Mac Pro that nobody else has, and it will also need to utilize Intel's fastest chips in order to dispel any notions of the system being weaker than the competition in terms of speed -- this is a dark cloud over the Mac that finally needs to be cleared.
Having two optical drives makes sense if one of the drives is going to be BluRay -- isn't BluRay incompatible with writing DVD and HD-DVD content? It would make sense if one of the drives was BluRay, the other was HD-DVD, giving Mac Pro users access to the full spectrum of DVD authoring hardware. If two optical bays are provided, I believe this type of configuration will be offered.
I'll be watching the announcement closely, although my Dual 2.5 GHz G5 (single core) handles everything I throw at it and has never ever given me reason to even want to upgrade. However, if the new Mac Pro hits 3 GHz I may be very tempted... if it doesn't, I'll wait it out. If the new high end Mac Pro doesn't go to 3 GHz like Dell and others, the Mac Pro will sink plenty fast.

Lee, you should already know my answer to that question. It's an emphatic "no." Nor do I support the gay rights movement.
I don't tell others what to do, but that doesn't mean I think it's all right for them do everything they want to do. I'll share my opinions with others if they're willing to hear them. I don't want to control anyone, and I will not be a codependent caregiver. I refuse to protect others from negative consequences when they need to learn from them.
But you ARE trying to control others Bill. It's quite obvious. There are no negative consequences inherent to being gay. I'm a 43 year old man, and quite happy. The only negative consequences I've suffered have been at the hands of people like you, who think you know how everyone should live and try to force your beliefs on us with laws. You absolutely want to control others, or at the very least, impose your punishments on us.
My parents, especially my Mom, hated to see me do some foolish things when I was a boy. They let me walk the half mile to the steakhouse when they knew that I probably would have been too tired to walk back home. They let me stand outdoors in the winter when I tried to run away from home in the winter. The front porch was too icy for me to stand on, so I couldn't walk down the steps.
Hmm...but did they make any laws against you doing any of those things?
I believe that people with same-sex attractions are endangering themselves at least physically when they have sex with each other. So I'll post a link to some evidence for my opinion (http://www.catholiceducation.org/articles/homosexuality/ho0075.html). Notice, the document's author is a medical doctor.
There are risks inherent in any sexual activity Bill, heterosexual or homosexual. I'm well aware of the risks of both. Apparently, you seem to feel that all gay men engage in sodomy, which is far from the truth. Also, many of these statistics are based on the results of promiscuous behavior. Gay people marrying would discourage promiscuity, which would most likely reduce those statistics. One would think you should be pro gay marriage rights in that case. But hey, we all know that's not what your real concern is. Your concern is to get everyone to conform to your rules.

Libya is more like Bosnia than Iraq. A moment of force has the potential to change the scope of the conflict, hopefully for the positive, in a way that a full-blown invasion would merely complicate. That's the central part that fivepoint, who is merely interested in making another partisan screed, is ignoring.
Well exactly. Far easier to tag together some buzzwords, maybe pull something from FoxNews than it is to think critically about the issue. This inane comparison between coalition numbers was also picked up by Steve M.:
Fox Nation huffily declares that "Bush Had 2 Times More Coalition Partners in Iraq Than Obama Has in Libya." Bush's thirty-nation list, of course, included such global powers as Azerbaijan, Estonia, Latvia, and Uzbekistan, and didn't include the likes of, y'know, Germany and France.
But if we're going to play games like this, in the run-up to the war, how many coalition partners did Bush attract per week? The Libyan uprising started just about a month ago and Obama's coalition is fifteen nations. When do you date the start of the "Iraq crisis" the Bushies manufactured? The Axis of Evil speech, fourteen months before the war began? The Battle of Tora Bora, a month before that? The first administration meetings on Iraq regime change, mere days after Bush's inauguration, and more than two years before the Iraq War started? By that standard, Bush barely acquired one coalition partner a month! Obama obtained more than three partners a week!
I'm reminded of the 2000 electoral maps that measured Bush's vote by geography, as if winning a county with more jackrabbits than people was the equivalent of winning a county full of apartment buildings.

Meanwhile, Juan Cole lays out ten reasons why this is not like Iraq:
Here are the differences between George W. Bush�s invasion of Iraq in 2003 and the current United Nations action in Libya:
1. The action in Libya was authorized by the United Nations Security Council. That in Iraq was not. By the UN Charter, military action after 1945 should either come as self-defense or with UNSC authorization. Most countries in the world are signatories to the charter and bound by its provisions.
2. The Libyan people had risen up and thrown off the Qaddafi regime, with some 80-90 percent of the country having gone out of his hands before he started having tank commanders fire shells into peaceful crowds. It was this vast majority of the Libyan people that demanded the UN no-fly zone. In 2002-3 there was no similar popular movement against Saddam Hussein.
3. There was an ongoing massacre of civilians, and the threat of more such massacres in Benghazi, by the Qaddafi regime, which precipitated the UNSC resolution. Although the Saddam Hussein regime had massacred people in the 1980s and early 1990s, nothing was going on in 2002-2003 that would have required international intervention.
4. The Arab League urged the UNSC to take action against the Qaddafi regime, and in many ways precipitated Resolution 1973. The Arab League met in 2002 and expressed opposition to a war on Iraq. (Reports of Arab League backtracking on Sunday were incorrect, based on a remark of outgoing Secretary-General Amr Moussa that criticized the taking out of anti-aircraft batteries. The Arab League reaffirmed Sunday and Moussa agreed Monday that the No-Fly Zone is what it wants).
5. None of the United Nations allies envisages landing troops on the ground, nor does the UNSC authorize it. Iraq was invaded by land forces.
6. No false allegations were made against the Qaddafi regime, of being in league with al-Qaeda or of having a nuclear weapons program. The charge is massacre of peaceful civilian demonstrators and an actual promise to commit more such massacres.
7. The United States did not take the lead role in urging a no-fly zone, and was dragged into this action by its Arab and European allies. President Obama pledges that the US role, mainly disabling anti-aircraft batteries and bombing runways, will last �days, not months� before being turned over to other United Nations allies.
8. There is no sectarian or ethnic dimension to the Libyan conflict, whereas the US Pentagon conspired with Shiite and Kurdish parties to overthrow the Sunni-dominated Baathist regime in Iraq, setting the stage for a prolonged and bitter civil war.
9. The US has not rewarded countries such as Norway for entering the conflict as UN allies, but rather a genuine sense of outrage at the brutal crimes against humanity being committed by Qaddafi and his forces impelled the formation of this coalition. The Bush administration�s �coalition of the willing� in contrast was often brought on board by what were essentially bribes.
10. Iraq in 2002-3 no longer posed a credible threat to its neighbors. A resurgent Qaddafi in Libya with petroleum billions at his disposal would likely attempt to undermine the democratic experiments in Tunisia and Egypt, blighting the lives of millions.

I don't know how many times we have to go round and round with this here. I've been on MacRumors since '01 and it's always the same-old, same-old. It's not legitimate. It's "I-wantism." You have no basis to believe that a Rev B would be more "stabled and refined." That's a hope, backed by nothing -- and nothing Apple ever comments on, either. The bottom line is that you can hope if you want, and you can wait if you want, but to bash Apple for being slow on the trigger, and to make the argument that Meroms are amazing and Yonahs are crap is, frankly, horse manure. Like I said, 64 bit is pretty irrelevant for most users, and the speed and battery differences are quite negligible. And the argument that Apple is losing tons of sales to PC manufactuers is, frankly, laughable too.
Well, I've been on MacRumors since last week and I'm already tired of posts telling me what I really need. I don't recall seeing posts saying Yonah was crap. Most people just want to feel like they are making a good investment on an expensive piece of equipment that may be around for 3-4+ years. I would like a laptop with a 64-bit processor. Period. I don't care what you think I need. The problem with posts like this are that they waste my time, and the time of other users who are looking for information on the release of the new MBP models.
Edit: I should add, however, that if anyone is willing to donate the money for me to purchase a new MBP, I will gladly accept all advice on said purchase.

You have 800 cars exactly as they were in GT4, so you'll get a good idea. :p
My buddy picked this up today, so I'll be checking it out on Friday when we hang out. I'm not buying it without trying first. It will be interesting to see how well it plays. After waiting 6 years for another full Gran Turismo, I have big expectations. But hey, even if it doesn't play as well as I'm hoping, the photo mode looks excellent. I can spend a LOT of time in there.

but is still more productive because it handles more calculations per clock cycle
I'm no processor geek. I have a basic understanding of the terminology and how things work so correct me if I'm wrong, but wasn't this one of the advantages that the PPC had over Intel chips? Does this mean Intel is moving toward shorter pipes? Are we talking more instructions per clock cycle or what? What does "calculations" mean in this context?
With most processors, especially the Intel/AMD processors, "instructions per cycle" is not a useful number. These processors have both simple instructions (add register number 3 to register number 6) and complex instructions (add register number 3 to the number whose address is in register number 6). A PowerPC has the simple instructions, but not the complex ones. Instead it would need three instructions "load the number whose address is in register number 6, and move it to register 7", "add register 3 to register 7", "store register 7 to the location whose address is in register 6". But the Intel processor doesn't magically do three times as much work. Instead, it splits the complex instruction into three so-called "macro-ops", and does exactly the same work. So in this case, the PowerPC would execute three times as many instructions per cycle (3 instead of 1), but because it doesn't do more actual work, that is pointless. Instead you would count the number of operations, and they are more or less the same.
Intel is indeed moving towards shorter pipelines. They have done that already with the Core Duo chips. Longer pipelines have the advantage that each pipeline step is a bit faster, so you can get higher clockspeed. Shorter pipelines have the advantage that they take much less energy (very important; at some point your chips just melt), they are much faster handling branches, and they are just much much easier to design. Pentium 4 needed absolutely heroic efforts to produce it, and would have needed twice the heroics to improve it. Instead, the Core Duo has a much simpler design, that is just as powerful, and because it was so simple, Core 2 Duo could improve it.
And Core 2 Duo can now execute up to four "micro-ops" per cycle, same as the G5, compared to three for Core Duo, Pentium 4 and G4. It also has some clever features that reduce the number of micro-ops needed up to 10 percent, and some other improvements.

Instead, the Core Duo has a much simpler design, that is just as powerful, and because it was so simple, Core 2 Duo could improve it.
And Core 2 Duo can now execute up to four "micro-ops" per cycle, same as the G5, compared to three for Core Duo, Pentium 4 and G4. It also has some clever features that reduce the number of micro-ops needed up to 10 percent, and some other improvements.

Apple better not win this case and anyone who thinks that they should are a fool.
I'm doing my fool dance right now...
We can dance if we want to
We can leave your friends behind
'Cause your friends don't dance and if they don't dance
Well they're no friends of mine
I say, we can go where we want to
A place where they will never find
And we can act like we come from out of this world
Leave the real one far behind
And we can dance :D
