meme( there is no perfect laptop to buy now )

I'm trying to replace my 4 year old powerbook. The battery lasts for less than 5 minutes and it's difficult to describe how slowly it runs flash. I'd really hoped that by 2008 I could buy a vastly more powerful computer for less money, but also that it would be much smaller. I'm not really in the mood to shell out top dollar for a 5.5 pound machine again. So, this leaves the new MacBook and the Macbook Air. Although the body of this machine looks quite nice, I can't really get into the black glass display with the large bevel. I'm not a matte snob, but I do prefer it. And the thing is still 4.5 pounds. This leaves the Air. I think it's a beautiful machine design, feels next-gen, and doesn't suffer from the black display uglification of the new units. It's problem seems to be performance. It just seems that you'd buy this thing for $1799 and then 12 months later it would be too slow. Maybe the newest updates have addressed this to some degree.
