I just purchased a Macbook Air and need to install Microsoft Office due to my work. I've been using Office 2008 on my other laptop and it's been fine. Now there are so many versions of Offices, 2011, 265, etc..I'm a university student as well. Should I get the university student 4-year subscription? Any pros and cons with that besides the attractive price point? I read it somewhere that you must be online to use Office with the university student edition. Is this true? Also, can I still purchase 08 or 2011? Please help me decide which version to get. Thank you very much!
