I want to put a SSD into my new 13" MacBook Pro, but I don't know if I should get a 64GB or 80GB. I'm going to install OS X and Windows 7 Professional. Outside of that I'm using D-Link's 2-Bay NAS for my music, photos, and other files. So, will 64GB be enough or should I go with 80GB to be safe? Also, what besides the OS should be stored on the SSD? Anyone have any insight on this?
