Vista is much better at making use of your memory through aggressive precaching. XP requires less overall system resources to remain usable is the correct phrase.
I guess. All I really care about is that Vista essentially requires double the amount of memory for no noticeable gains in games.
Windows 7 is essentially XP's lightweight with Vista's features and there is no real reason to stick with XP anymore given that Windows 7 also has amazing hardware compatibility and software emulation for old XP binaries.
The hardware compatibility wasn't quite amazing when I tried it. I couldn't find any drivers for my sound card. I had to use unofficial hacked Vista drivers. As for software emulation, from what I've read, it only works for games that don't use 3D acceleration.
