OK, please be gentle, since I am a newbie to Mac, having recently purchased a MBP 2.2/2/160. (Although I will proudly say I owned an original Mac 2 and a Duo a LONG time ago, and had to move to PC because of business needs. It feels great to be back home). I've already purchased Parallels so I can use some Excel software that won't run on the Mac version of Excel (go figure). I am thinking of using Bootcamp + Parallels, using Bootcamp more for games and occasional speed needs. I am wondering if I should wait until Leopard to install everything? Would I have to reformat, reinstall, etc., or can I install now without much hassle when Leopard finally gets here? Also, any thoughts on whether Leopard's version of Bootcamp might make Parallels obsolete?
