So far my list includes: MSN and AIM Open Office (for excel, powerpoint, and word) What program can open .doc files? (when I open them through open office on my PC, I see gray squares). What video player should I install? What program can open .pdf files (does Adobe work on a Mac OS)? Does Limewire work on a mac? I can't think of anything else that I'll need because I'm mainly using this for school and watching porn videos. Are there any other programs that I need? I won't be using Windows at all.
