If you are not using the computer in an area where Microsoft Servers are installed (i.e. an office) - anything more than Windows 7 home edition is a waste of money....

(this is a very abbreviated statement - if you want the two page technical description - see: http://en.wikipedia.org/wiki/Windows_7_editions)
