Hey, Im probably only hours away from walking 300m to the apple store to purchases the 13 MBA 1.86Ghz, 4GB ram. There is only 1 thing stopping me: Its an 8 pages thread on the apple forum about a strange buzzing noise coming out from the left side of the keyboard on the MBA. If you are in a quiet room and have good hearing, you could hear the noise. It will not increase with fan speed. People seem very annoyed/irritated whit it. I have good hearing and I absolutely hate small strange noises. A constant light breeze from the fan is perfectly fine though. But the noise they describe would make me stop using it in a couple of days. When I read thru that thread I started thinking about getting the new base MBP with 128GB SSD instead. Same price, better performance, worse mobility. But then there is the heat issue. As you can see Im quite confused. But when u spends this much money on a product you want it to be perfect. So, I hope for some help from you guys. Any of you heard this noise?
