First, to Scottsdale: Thanks for getting into my head about the SSD nonsense. Now I cannot bring myself to pull the trigger on the low end Rev. C Air. I keep worrying about performance! In the Apple store I tried out both and there is a considerable difference; it took about 10 seconds for the HDD to open Pages, compared to 2 bounces for the SSD. Is excessive heat still an issue with Rev. C MBA as it was with Rev. A (I've read that it was a big problem)? I'm not comfortable cracking open the air and reapplying thermal grease, so stock is how I intend to use it. I've been known to occasionally get sucked into viewing a couple hours worth of YouTube videos (never HD), and I worry that doing so on the Air is going to kick the fans up to 6200 and annoy me. What's everyone's experience with the high end Rev. C when it comes to heat? Is it as bad as some people make it out to be?
