I have a 2008 MBP with 4 GB ram. My plan: 1) Upgrade to snow leopard 2) Install windows 7 w/ boot camp 3) Install parallels and use the boot camp windows 7 What I plan to use each OS for: - Mac: 90% of what I normally do on the computer - Parallels w/ Windows 7: Microsoft excel (since the excel for mac is impossible to use... shortcuts are all different), other office programs... and that's about it.... - Bootcamp w/ Windows 7: Intensive windows-exclusive programs My questions: 1) If I load windows 7 from bootcamp with parallels, am I still unable to access the same files (excel files, etc.) between OSX and parallels because of the bootcamp partition? I understand that through boot camp windows 7, you can't share the same files - does it matter if I use parallels to load the bootcamp windows? For example, if I'm actively working on an excel file, I would use parallels. But if I just want to glance at an excel file, I'd probably want to just load it in OSX instead of using parallels. 2) Is parallels a solid choice, compared to vmware fusion or citrix - based on my usage as described above? THX!
