I will be soon taking stock of my i7 iMac and so will want to upgrade from current Office 2004 to something Intel native. I've been thinking I'll skip Office 2008 for now and give iWork or OpenOffice a try. But Microsoft currently has a deal for students where I can buy Office 2007 Ultimate for Windows for $64 which is a really great deal. What do you think? Will it work well running Office 2007 in Parallels on my 27" i7 (it will have 8GB RAM) or am I better with Office 2008 Student and Teacher for Mac?
