How do they compare? Are the features generally the same? Are there things you can do in one but not the other? I'd like to hear from some people that have used both and can give me some advice. I have to use Office 2007 for a class of mine this semester and I've had to install XP in Boot Camp to run it, since the instructor told me that an '08 Mac version will be way different and won't have the same features. Could Office '08 for Mac be that drastically different from Office 2007 Professional for PC??? I guess the reason I'm asking is because I HATE HATE HATE using Windows on my new alu iMac - it's basically sacrilege. The reason I buy Mac is so I don't have to deal with stupid Microsoft garbage. If I can find a way to use Office '08 for Mac instead of Office 07 for PC - I would be so happy. Any advice?
