I'd like to say that I just restarted my crap-ass Dell here at work for the 2nd time today. It's a 14-month old Dimension 4150 laptop and it sucks massive ass. I was running Netscape 7.1, Word, and ChemDraw (I'm a chemist). And the damn thing freaks out.
The 4-5 year old Pismo Powerbook I have about 2 feet from it? Hasn't been restarted since last year.
You want a computer you can do all the word processing, spreadsheets, presentations, graphics, etc, get a Mac. You want to browse the internet? Get a Mac.
You want to play games? Buy a Neo-Geo. Or a PS2. Or a GameCube. Or god forbid, an XBox. As it turns out those things are made for games. A PC is made as a means to pay Microsoft money.
Seriously, other than the "games", there is very little reason to buy a Wintel PC.
Buy a PowerBook. You'll be glad you did.
