In fact I've done several upgrades for people so far (about 6 or 7) and have yet to run into a single driver issue with any of them, so no offense but I think you're kind of speaking out your butt on this one and offering unfounded information & advice
I've done one and a half installs of it. One failed, the other worked but I can't get drivers for the graphics card so it's stuck in non-accelerated XGA on a WUXGA display, which is pretty useless since it was my media player machine
My arguments here have mostly been about why I think people are missing the point with their reasoning for buying it. For example, Wushumonste just said that he installed it because it was free - which isn't a reason to install something, I'm not particularly trying to bash any particular operating system, though my last comment was a not-too subtle dig at the industry for being all close-source. If there were open source drivers for stuff, then odds are I could recompile them on my media system and I wouldn't have this problem - and then I'd be able to use windows 7 on it. Not explicitly a Microsoft thing, but they're a bit like the ringleaders.
