Thermals: The Leg Test
At the end of my 2010 15-inch MacBook Pro review I mentioned that the bottom of the chassis can get uncomfortably warm. The higher peak power draw of the Core i5/i7 combined with the discrete GPU of the 15-inch MBP can result in more heat dissipated than the previous model.
The 13-inch MacBook Pro is built off a mature yielding 45nm Core 2 Duo CPU. Given how long Intel has been making this CPU it's safe to assume that this chip is running as cool as physically possible. While the mobile Core i5/i7 still have a lot of improving to go through. While the base of the 13-inch MBP can get warm under normal use (aluminum conducts heat very well...towards your lap), it's not as bad as the new 15-inch. I'd say it's pretty much on par with last year's models.
To quantify these differences I pointed an infrared thermometer at the bottom of a few MacBook Pros and reported the surface temperatures. They were taken in a room with an ambient temperature of 76F.
At idle the 13-inch MacBook Pro is about room temperature. The new 15-inch is a few degrees warmer and the 2009 15-inch is actually the warmest. Remember that the Core i7 in the 15-inch has a very low idle power thanks to Intel's power gating.
While browsing the web the temperatures climb up considerably. The new 13-inch is still cooler than anything else, while the new 15-inch model's power efficiency let's it run cooler than the previous model.
Running Half Life 2 Episode 2 changes things dramatically. Now all three machines are running at or above 90F and the 2010 15-inch MacBook Pro is finally warmer than the previous model. If I measure temperature near the exhaust fan on the notebooks the new 15-inch model peaks at 105F compared to 99F for the previous generation and 92F for the 13-inch.
In all cases the new 13-inch MacBook Pro keeps surface temperatures under control. In most situations the 2010 15-inch MBP is actually cooler than the previous generation, it's only when the dGPU is active or under heavy load that the surface temperature can go well above what the older model would do.

Why do people treat Apple like they're the only person that uses Foxconn? HP, Dell, and others use them as well. I'm not excusing anything at Foxconn, but to single out Apple as only being able to do this because of who they use for manufacturing, when most other top companies use the same vendor, is ridiculous.james.jwb - Wednesday, June 9, 2010 - link
@jabberYour comment pretty much applies to 80% of everything you buy, period. You are living in a bubble and possibly even a hypocrite to get on your high horse about this product, or Foxconn so singularly.
But hey, it is being heavily talked about at the moment and it is in your face, so good for you for having this fleeting feeling of misplaced superiority that will no doubt disappear just as quickly as the misplaced headlines.

Fully aware that any electronic device has blood sweat and tears on it so I am fortunate enough to purchase it.I have been very aware of this for years.
However, it's been pretty apparent that many havent been aware of this and seem to wish to keep their heads in the sand so they dont have to feel guilty about it.
"I dont care what goes on as long as I get my new iPhone upgrade gimme gimme!"
The suicides at Foxconn are not necessarily Foxconn's fault.
It's OUR fault!
Our fault for wanting to only pay the minimum for more and more good such as these Macbooks, motherboards, GPUs etc. etc.
I just hope from events this past few weeks might make a few people think a little bit more before they purchase their next unnecessary electronic gadget.
Same goes for cheap, shoes, clothes, jewellry etc.

95% of mac users don't use their GPU. The Intel GMA HD GPU would have been more than enough for this kind of laptop. The Geforce 320M is too slow for gaming anyways so I don't see the point.jabber - Wednesday, June 9, 2010 - link
Noooo, dont be silly. The Geforce 105M in my Dell is more than enough to play a lot of the games I mess around with such as BF2 and Eve online. Eve plays at high settings and gives around 60fps.We dont all play Crysis and Call Of Donkey Modern Warfare 4 whatever.

Maybe more would if it HAD a GPU to begin with.If the current Mac users do not buy their machine to game on (or any other GPU intensive task) because there is no good GPU present, what is to say they will not buy and utilize it if it is included?

Not true, the OS X desktop has always leaned heavily on the GPU. The other thing is OpenCL which shipped with OS 10.6. Apple has to be prepping some major GPU computing in the next version of OS X, especially since it is a part of 10.6.I believe this is the "thing" Anand is waiting for, we'll see. It makes sense why Apple would put such a relatively high baseline on their GPUs, otherwise they'd just go with the Arrandale's anemic graphics and call it a day.

They took away support for jumbo frames in the Broadcom ethernet chip.:-(
Big minus if you tune your NAS.

Uh, I call bull.
Apple fit a three-chip solution in the first MacBook Air. Yes, the CPU was on a smaller mount, but it was still a three-chip solution on a microscopic board. If they really wanted to, they could slap a three-chip solution in the 13" MBP.

1) The MBA had the CULV C2D and GMA950 or 9400M. That's two!2) The MBA is 13" but it also using a SFF chip, has low power and low heat, thereby needs less venting and can use a smaller fan and heatsink.
3) The MBA has a 1.8" drive, not a 2.5" drive.
4) The MBA has no optical drive whilst the MB and 13" MBP do.

If you're going to call "bull" then i assume that you have detailed info as to where all this extra room is that a Core-i chip + dGPU + additional fan would go in this system.
it seems to me that the only way they could add the items you think are so easily included which altering the dimensions of the internal space is to reduce the size of the battery (which is still too lower than most people would like it to be at) or remove the optical drive (which oft goes unused, is slow, mote prone to break due to moving parts, and takes up 25% of the internal space). I'm going with the latter.
