I routinely run Windows 7 in VMs (generally VMWare) and get near-native speed for anything except GPU-bound tasks. It's also rock-solid stable. So I'm curious about your problems you mention you keep having. My general experience (for a fairly broad spectrum of users) is for most relatively-recent hardware (e.g. >2GB RAM, half-decent IGP, etc.) Windows 7 is as-fast, faster and a lot more productive than XP (the last due to general UI improvements).
