Unless you have an extreme PC...Adobe makes no sense (unless you are using the Quadro nVidia cards in a Mac Pro). Sure, the Merc engine increases performance for a few transitions and filters....but rendering is still necessary in MOST cases!
Premiere Pro makes sense in a lot of cases for Mac users. It makes the most sense for After Effects artists, like yourself, as you can dynamic link directly to After Effects from the Premiere Pro timeline. As you pointed out, Macs work great with Premiere Pro and the NVIDIA Quadro 4000 card. More and more cards are being supported as time moves forward. Want a certain card to add Mercury Playback engine hardware acceleration? Make a request here: http://www.adobe.com/go/wish
Not sure what you mean by "unless you have an extreme PC, Adobe makes no sense?" Yes, you need more RAM and a decent NVIDIA card to make Premiere Pro really fly on a PC-it's a 64 bit application-but even modest PCs do just fine with Premiere Pro. If Apple puts out a 64 bit application, you can bet that you should be looking at upgrading your Mac with a lot more RAM, more cores on the GPU, etc., as well. Need more info on tuning your system with Premiere Pro? Watch this: http://tv.adobe.com/watch/learn-premiere-pro-cs5/optimize-a-computer-for-mercury-playback-engine/
You wrote that rendering is still necessary in most cases. Really? What kind of system are you on? I've never had to render, even on my '09 MacBook Pro with no NVIDIA card and the Mercury Playback Engine in software mode.
You say that CUDA accelerates only a "few" video filters and transitions? There are a lot more than that! Upgrade to Premiere Pro 5.0.3 and you'll see the following GPU accelerated effects:
- Alpha Adjust
- Basic 3D
- Black & White
- Brightness & Contrast
- Color Balance (RGB)
- Color Pass
- Color Replace
- Crop
- Drop Shadow
- Extract
- Fast Color Corrector
- Feather Edges
- Gamma Correction
- Garbage Matte (4, 8, 16)
- Gaussian Blur
- Horizontal Flip
- Levels
- Luma Corrector
- Luma Curve
- Noise
- Proc Amp
- RGB Curves
- RGB Color Corrector

MS Windows has about 95% of the world market...doesn't mean the technology is better.:)
There is a huge difference between an OS and a cellphone standard. Having two cellphone standards is like having two internets. You as a customer have no idea weather you use CDMA or GSM. I dont know about you, but I use my cell for talking end send/receive data. I dont give a rats ass whether this done through code division or time division...

A 2.66 Ghz Woodcrest will probably be faster than a 2.93Ghz Conroe. A 1.83Ghz Yonah is faster than a 3.2Ghz Pentium, right?;)
Merom, Conroe and Woodcrest all use Intel's new "Core Microarchitecture" (a bit confusing: Core Duo does _not_ use "Core Microarchitecture", it is basically an improved Pentium III. The Core 2 Duo chips use Core Microarchitecture).
All three chips produce the same performance at the same clockspeed. Cache size may make a difference, but the Conroe models starting at 2.4 GHz all have the large 4 MB cache. So a single 2.66 GHz Woodcrest will be substantially slower than a 2.93 GHz Conroe. Not that it matters; the 2.93 GHz Conroe is extremely overpriced and unlikely to be used in any Macintosh.
I personally would expect 2.0GHz Conroe, 2.66 GHz Conroe, 2 x 2 GHz Woodcrest and 2 x 2.66 GHz Woodcrest for a wide range from cheap to maximum performance.

so i'm having a difficult time deciding what to do.
North Carolina's sales tax holiday is this coming weekend, just a couple of days before WWDC (of course!). i had every intention of buying a MacBook Pro during the holiday, but now i have no idea what to do.
assuming there's not a silent release of an updated MBP tomorrow...
will waiting be worth losing the 7.5% (somewhere between $150 and $200 depending on how i customize it) that i'll have to pay if i don't get it during the holiday?
should i go ahead and get it during tax free weekend in case there's not even an announcement at WWDC? or, if there is an announcement, should i go ahead and get it and then return it within the 14-day window, losing the 10% restocking fee.
so many options and this first-time mac buyer doesn't know what to do!

AMEN! ...ahem.. I mean +1 :D
side note: it's silly that I have to state that I own a bunch of Apple computers/devices when I criticize Apple.. or else I'm in danger of being called a "troll".. I think that those who call others "trolls" are either immature, or have nothing to really add to the discussion.

See Apple???
Yet another potential customer for iMac Ultra. We Want C2DE + X1900 and a 23" screen!
It has been demonstrated an iMac can take large amounts of heat. I should expect (With almost certainty) that iMac will get at least 2.4 Conroe, which should be quite a significant increase on its own, and possibly higher. 2.4 on the low end 17" model, 2.66 in 20" and the option of 2.93 or 3.2 in iMac Ultra! (Then Apple can gift me with one for coming up with such a great idea)
X1800's for the 17 and 20 inches, and X1900 for the 23".
Sounds good to me.
Extra space due to 23" could be used for the cooling of the twin fires of CPU and GPU.
Yup, heat is no problem. :) Cost on the other hand is. Going from a 2.4 GHz Conroe from a 1.83 GHz Yonah on the low-end is roughly a 30% increase in cost JUST for the CPU. As for your "iMac Ultra"...
$1000 - 2.93 GHz Conroe
$800 - 23" Display
$300 - X1900
$400 - Hard Drive, Optical Drive, RAM etc.
+ Build costs, marketing costs, logic board cost, casing costs etc.
+ Apple's profit margin
And you are easily looking at a $3000 machine.

lol... You really think Intel is the reason Apple laptops cost what they do? Really?
I never said I considered it overpriced.
I was making a point that it's now underpowered for some users and less powerful than the previous model.
And another point... I'm not really blaming Apple. Obviously, it's Intel's fault for forcing the Intel graphics on Apple, among other companies that plan to use the new CPUs and Intel logic boards.
For many people with the current model, the new Macbook Air will be a downgrade unless you really need some of the other new features.

The trouble is .. I find the TDP numbers for Sandy Bridge very misleading. For example the previous i7 2.66Ghz dual core had a TDP of 35W and the current i7 2.2Ghz quad core has a TDP of 45W. Theoretically, it should only use 10W more when doing CPU intensive task, but according to anandtech who measured the task, the i7 Sandy Bridge Quad core was using almost 40W more when running cinebench.
http://www.anandtech.com/show/4205/the-macbook-pro-review-13-and-15-inch-2011-brings-sandy-bridge/14
It just doesn't make any sense. Going by those figures, if the i7 dual core was 35W, the i7 Sandy Bridge quad core would be around 70W.
Not sure how this relates to potential MacBook Air Sandy Bridge processors, but keep in mind.. there must be a reason why Samsung went for the ULV processor in their 13" laptop instead of the LV one.
CPU isn't the only thing that changed. AMD 6750M (~30W) has higher TDP than NVidia GT 330M (~23W). I had to put ~ because their TDPs are not officially stated by AMD or NVidia so it's just based on previous GPUs and their TDPs. The point is that AMD 6750M has higher TDP.
There is also another thing. TDP is not the maximum power draw. Maximum power dissipation is usually 20-30% more than the actual TDP. While MPD is rarely achieved as it requires maximum voltage and temperature, it can (nearly) be achieved with heavy benchmarking applications.
For example, the combined TDP from quad core SB and AMD 6750M is 75W. If we use 20% extra as the MPD, that is 90W, just from the CPU and GPU! Of course those parts are not using 90W in that test because things like screen, HD, RAM etc need power too. As the MPD is usually in percents, it can explain why the difference is so big in watts.
40W sounds a bit too much to explain with MPD though. IIRC the GT 330M is underclocked but I'm not 100% sure. You have a valid point that the SBs may be using more power than their predecessors. To make this more accurate, we should compare them with C2Ds though ;)
I guess we will have to wait and see, but an ULV in 13" would be more than a disappointment.

But as some already pointed out, many applications can't use multiple cores, therefore you won't get any performance improvements with multi cores.
A single application, if not multithreaded, won't see any performance boost.
But if you're running multiple applications at once, your overall system performance will definitely improve.
Also note that many of Apple's system facilities (like Core Image) are internally multithreaded. So apps that use these system services will see performance boosts even if the application developer didn't write any multithreading code into the app.
I am also certain that we'll see more and more developers using multithreading, now that all but the cheapest systems sold will have at least two cores. Especially with those apps that are CPU-intensive, and could therefore gain the most from multiprocessing.
(Gee, it seems like it was only a few short years ago that we were having this same discussion about AltiVec :) )

Where you are going to see the difference is when you multi-task.
For Example: Burn a Blueray disk, render a FinalCut Pro movie, download your digital camera RAW files into Adobe Lightroom and run a batch, and watch your favorite movie from the iTunes Movie Store all without a single hiccup.
Bingo. Check how many processes are running on your computer right now, and you'll see why more cores can help. Writing a program to use multiple CPUs is complicated, yes, but OS X is already written to spread programs across multiple CPUs automatically.
It will take a while for people to come up with effective uses for that, but given the power we will find it.

I tested Lion, and removed it after a month. Not buying it. I'll use Snow Leopard, it's the best OS so far. I'll see the one after Lion, maybe there will be something interesting.
This is the problem of non-developers getting access to software that is not intended for the public. People install it, expecting it to have all the stability and features of the final version and get disappointed when it doesn't. And people wonder why Apple is all about secrecy and NDAs.
You shouldn't have installed it in the first place. Look at it when it is released and make your decision.

Is having more cores more energy efficient than having one big fat ass 24Ghz processor? Maybe thats a factor in the increasing core count.
Absolutely.
The power consumption of a chip is proportional to the clock speed, multiplied by the voltage squared. So at the same voltage, a hypothetical 24 GHz chip would use eight times as much power as a single 3 GHz chip, and the same as eight 3 GHz chips.
However, with any given technology, you need higher voltage to achieve the higher clock speed. So with the same technology, that 24 GHz chip would need much much higher voltage than the 3 GHz chips and accordingly it would take much more energy than eight 3 GHz chips.
As an example, some iPods have two ARM chips running at half the clock speed and lower power instead of a single ARM chip running at higher speed, in order to safe power.
