I haven't hammered on mine much but thus far I like it. I haven't had the buzzing issues that others have but I HAVE noticed the limited WiFi range. Sadly, EVERY Apple notebook seems to suffer from that. Also, the Expresscard slot, I"m sure, will be nice to have about three generations down the road. Right now, I think it's insanity that they put it in. There's not an Expresscard on the market at current and what I want (datacards) likely won't be out for a year or more. Yes, I know bluetooth is an option. Tethering is a PITA. I have to worry about another phone, another charger, another battery to maintain. Also, show me a Cingular 3G HSDPA bluetooth phone I can buy right now. The backlit keyboard is really nice in low light situations. It also is leaps and bounds faster than the 867Mhz 12" Powerbook I have had for the past few years. I will say that it doesn't seem quite as well built as Apple notebooks that've gone before. Specifically, the trim around the mousepad feels flimsy. Apple notebooks previously have had design issues but their build quality has been impeccable. I can't comment on the battery life as I haven't had occasion to use it away from the plug.
