Oh they say they don't do things like introduce bugs but lets face it, if they want people to buy vista, they could do something as evil as introduce a bug into the next and presumably last security update for XP. But will they, well who knows, if someone in programing has a lot of stock in MS and they want to sell it while its on the high side, what better way than to force people to upgrade. Not that these kind of thing never happen and all. No, they would never do such a thing.
Bring this up in two years if were still around here and then we can talk.
Ya building your own system is fine, but there are set backs. Its better that you let someone else build it for you. They also seem to get better prices on parts do to bulk purchases and they warranty their products. If you build your own system and screw things up, your screwed.
