To say I'm dissapointed with the latest 13" MBP is an undestatement: no matte/hi-res screen option; no SSD as standard; poorer battery life, same weight etc - not to mention the same, sharp unibody style I've never liked. I put off buying an MBA and waited all this time for the new 13" MBP only to discover it wasn't worth waiting for. What I do want is an MBA - still can't decide between the 11" and 13" even after playing with both at the store, but am leaning towards the 13" as it has better battery life and a bigger screen. What I don't want is the same issue I had with a white iMac I bought a few years ago that had a buzzing fan that drove me mad. Apple wouldn't/couldn't fix it, and it was left up to me to pull the bloody thing apart and modify (remove) the fan housing and replace it with a custom styrofoam mount that absorbed the vibration and didn't amplify the sound. Design fault fixed. (And no fires - LOL!) I've been a Mac owner/user for almost 20 years. Just about every new Mac I've bought since my old "beige box" G3 has had hardware problems and needed to be fixed (or I've had to do it myself). I have a late 2008 15" MBP (last of the Al's) that, touch wood, hasn't given me any real problems. But alas, it's got the suspect 8600M GT GPU in it, so it's probably just a matter of time . . . So my question is, the new 13" MBA with 2.13GHz and 256GB SSD seems to be the model with most of the heat/fan-noise issues - is that correct? I don't need the 2.13GHz CPU and I can probably get away with the 128GB SSD. I use my machines for nothing more strenuous than surfing, streaming, Photoshop, word processing, playing movies/music and possibly flight simulation (I'm a pilot) hooked to a screen (though my 2.5GHz 15" MBP is still quicker than the MBA, so I'll probably continue to use this). However, my laptops travel everywhere with me, so lightness/durability/battery life is most important - that's why I want an MBA to complement my 15" MBP. Are the 1.86GHz CPUs appreciably cooler? Does a 128GB SSD run cooler than a 256GB SSD? I hear also that the Samsung 128GB SSD is actually faster than the 256GB SSD - is this true? My theory on the fan noise is that it is another Apple design fault - that the MBA has amplifying channels inside it for the speakers and that these same channels amplify the fan noise (if the fan is noisy to begin with!). I'm leaning towards a base model 13" MBA with 4GB RAM, as these appear to have had the fewest problems (simply from reading these forums and searching the Net). I can live with the specs, but should I really be considering the 11", as I understand the CPU generates about 70% less heat? I know a few things about pulling laptops apart, but I'm no expert by any means, so any technical advice appreciated. Thanks.
