Risser

Hi Guys, I'm trying to remove the hardware from the equation when imaging client PC's; like we do with server VM's these days. Has anyone tested the idea of virtualizing client pc's like we do servers? It would save time with image updating/creating across multi-platforms etc. Just not sure if the client/students would see or feel a noticeable performance decrease using a VM'd xp/win7 vs the a normal install? It also would save a huge amount of time when you do your hardware upgrades. Thoughts?
