After a while of using Vista, than you start to miss those small things in XP. If you are gonna get a new pc get vista, if you are gonna get a new pc and place a lot of old hardware inside, get xp but think if you need to move the actual hardware.
To me the main issue with not getting Vista is the mess around the drivers, while everything works ok for new hardware, older hardware is still a mess. x64 drivers are also still buggy some of the time, my machine bluescreened a few times because of the realtek x64 driver, luckely there is a new driver which solves the issue, but still.
My vista 32bit box had no problems at all, is that luck or
