Man $10 for VMW, tough to not pass that up... I'm using Parallels 5 now, but its a bit slow and laggy... was going to jump on 6, but $50 vs $10 tough call
I'm in the same situation as you. I've found Parallels 5 to be quite laggy so am interested to try VMW for $10 rather than fork out $50 for probably a not so imrpoved version of Parallels 6
