I have Vista Business running on my MBP. I have thought about upgrading to Windows 7 but I dont really want to spend $130 on omething I hardly use. Now I maybe only use Windows once a month for a couple things but I a going to be getting a psp go and that requires windows as of now. So windows runs pretty slow and shaky. I have a MBP 13" 2.26 with 2gb ram. If I upgraded the ram to 4gb with that improve my experiences? If not is there anything you can think of that would? Also I want to upgrade my hard drive to 500gb and if I use time machine to back up my data will it save the windows side also? Thanks for your help!
