Hi everybody. I am completely new to Mac. I am thinking about making the big switch from PC and was wondering what the thinking is about iMac vs. Macbook. How do they currently stack up against each other? Portability is a small factor for me, but by buying a MB, are you sacrificing a better machine for portability? Also, what is the thinking out there about Parallels vs. Fusion vs. Boot Camp? Finally, any thoughts on iWork vs. Office for Mac? Thanks in advance!
