Almost two weeks using the 11 inch MacBook Air. Sad to say, I'm seriously considering returning it. Two reasons. One, for no apparent technical reason, Apple has disabled booting into 64-bit kernel mode. The hardware supports 64-bit but it has been disabled on the MacBook Air. It's like buying a 200 mph Ferrari with a 180 mph speed limiter. Just on principle I should return the MacBook Air.
Two, the font is just too small to read. This is my real problem. 1366 by 768 pixel on an 11.6 inch diagonal screen makes text on every web site I visit too small for comfortable reading. I have to resort to zooming in on Firefox but this causes page layout to get all screwed up because pages aren't designed for 30 point font. The alternative is to change to a different resolution but this causes blurriness and distortion. Maybe if my eyes were 10 years younger, but right now it's just too much strain on my eyes.
Tough call. It's such a pleasure to use in every other aspect. So thin and light I barely notice it in my backpack. Very quiet, super fast bootup/resume thanks to the flash storage. There's a 14 day return policy so I basically have 1 day to decide...
