Thanks QS.
#1. I did some research and I concluded that Bootcamp(XP)+Leo with Fusion ver 2.* would be the best combination. If I get the notorious activation issues I will keep you posted. I am backing up my drive for testing.

#2. Newest is not always the best... I'll see if I like the new glassy (glossy too) display at the Mac Store. I love the new single piece base but I am not sure if I am ready to shell out 3G.
