I'm wondering what the interest is here on the forums for a realistic 15" MacBook Air. I've done some analysis on my professional blog (TechPerfect) and I think that a 15" MacBook Air would end up looking a lot more like today's airs than today's MacBook Pros. The gist of what I posted on TechPerfect is that in order to fit the Air form factor, Apple will likely have to stick with 17W TDP CPUs from Intel. Intel has already announced the initial round of mobile Ivy Bridge CPUs, and there are no quad-cores to be found at 17W. While Apple has gotten access to some pre-release stuff before, I highly doubt that Intel will be able to get quad-core in 17W. Also due to thermal, power, and space constraints (even with going to 15"), you're likely to see a loss of dedicated graphics, as dedicated graphics eat up a lot of power and heat. Lastly, you'd likely continue to have integrated RAM, even though Apple would probably bump the number up a bit. So, that all being said, would you rather buy (details here: use the poll): 1) 15" Air: Dual-core i7 (w/ HT) 3667U @ 2.0GHz, 8GB RAM (not upgradable), Integrated graphics, 256GB SSD Stick 2) 15" Pro: Quad-core i7 (w/ HT) 3720QM @ 2.6GHz, 8GB RAM standard, upgradable to 16GB, Integrated+Discrete Graphics, Hard Drive and Optical Drive remain standard. 3) 15" Air/Pro Hybrid: Quad-Core i7 (w/ HT) 3720QM @ 2.6GHz, 8GB upgradable RAM, Integrated+Discrete Graphics, 256GB SSD Stick (no Optical Drive) A little further explanation of #3-- No rumor has pointed to this, it's just a wish of mine. But this would be something that isn't quite as thin as an Air, but is thinner than the current Pros.
