The only reason people are switching to Vista is for DX10. Of course, when the Alky Project
matures, that won't be necessary and Microshaft won't have much to draw people to Vista anymore. I'm currently running XP for iTunes and a few other programs, but when Sabayon 3.4 comes out my second hard drive will be solely used for that.
A friend of mine has Vista, my dad has Vista, and some others I talk to online have Vista. They all HATE IT with a passion. It constantly asks you "Are you sure you want to perform this action?" Why the F*** DO YOU THINK I LOGGED IN AS AN ADMINISTRATOR, NAVIGATED MY WAY HERE, AND CLICKED THE 3 PREVIOUS OK'S???!!!!!
I thought XP used enough system resources as it does, but Vista is just an excuse to drain your hardware of its full potential.
In response to the original question: I won't get Vista, period.
The DRM, annoying re-asking of confirmation dialogues, the need for a new high-end computer, and low backwards-compatability make it not worth my few hundred hard-earned dollars.
