I dont have much expirience with vista, but I have a hard drive with regular xp, xp-64, and a beta of win7, and to be honest I'm loving win7. There are a few quirks, but then again, I stuck with xp all of the way through the vista period so it's gonna be a while till I get out of old habits. I have new hardware so almost all of it was recognized basically instantly, and worked seamlessly.

I dont know why people expect a browser with the os automatically. an os, and browser are two different types of software, thats like saying my os should come with halflife2 or microsoft access. Sure some computers come with them, but I'd never buy a computer bloated with software I didn't choose to get.
