I recently went to Best Buy and looked at the Macbook air. I really want one, but when I was playing around with it, I noticed that it was extremely sluggish. Spaces lagged like heck and it took nearly half a minute to get Photobooth and the iSight up and running. Is the computer really like this or is this just a messed up display model? Switching between apps was a bit slow too. Also, is the air the right computer for an accountant? I'm not really sure what programs I'm going to run in an Accountant program. I might edit the occasional video with imovie too.
