I have a new MacBook Pro 2GB 2.6 GHz, Leopard OS, and I need to use a Windows version of Adobe CS3 on this notebook. I cannot afford to buy this software in a Mac version also and I want to continue using my current version on desktop PC. I have purchased VMWare Fusion, thinking I had a new copy of Windows XP I could use. When I finally unearthed the box it is only an upgrade, one I never used on an old computer when XP first came out. Now I have to buy Windows as well. Can I buy and legally use an OEM version on this notebook? Does anyone have experience of running CS3 in Fusion with Windows XP or Vista? I have not used Vista much, and so far I have not enjoyed the experience. I am drawn to staying with XP, but I would welcome hearing other peoples' experiences. Please do not get too techy with your answers, LOL here (Little Old Lady)
