Drivers? The only drivers you'll ever need are graphics drivers, and that's only if you're a gamer; otherwise the default video drivers work just fine.
This is of course anecdotal, but on my computer every time I install win7 I need to go looking for video, sound and modem drivers to even make it behave like a modern computer (and I still can't believe Windows asks me if I want to search the internet for those modem drivers). Then I have to install a bunch of other minor drivers to get all the functions back. And this with a dell laptop that came with win7.
