I'm scoping out the applications that I'll need to get for my new MacBook Pro. I'm making the leap from PC to Mac for my personal computer, but I still need to retain interoperability with the MS Office suite for my work needs. I've seen the MS Office for Mac package, but I also understand that MS Office for the Windows platform can be run on XP or Vista in a VM environment in OS X. Setting aside the obvious costs for the additional software, is there any advantage to Office for Mac versus the alternative? Which works better?
