Was just looking for some advice on which virtual machine you guys are finding works better on Snow Leopard. I have Parallels 4, which I had on Leopard as well, with windows XP. Pn leopard it ran beautifully, however since upgrading I find its unbearably slow, and causes my whole system to slow down. I dont know if this is with parallels or with my system in general, as I have had a bit of trouble with Snow Leopard, though I believe I have sorted that out. How have people found VMware to run in comparison to parallels? Is it worth switching?
