I just got my air a few days ago, as a 2nd computer, a portable to go with my desktop. however I am finding that it is actually a bit too slow for my needs (i got the 1.6/80gb), even as a secondary computer. I kinda wanted to use the air as my appletv device - to watch all the things I've downloaded on my desktop on my HDTV, which is in another room. Loading up youtube and flash heavy sites seems to make the fan speed up to full blast. Watching divx movies also makes it spin up to max. Some video files (notably RMVB real player files) play very jerkily and result in dropped frames, but usually the audio is alright. All in all, quite disappointing as its a nice little machine otherwise. Just the dropped video frames and fan spinning up to max to watch files is kinda hard to live with. Anyone else finding this with their air?
