Windows 7 looks cool . BUT , it has compatibility issues with some programs
If you are Odin Diet user , its not working as of now on windows 7 . ( If any one tried and got it working please let me know ) .Some ftp applications also have compatibility issues .
To run XP mode on windows 7 , your processor should support virtualization. Your processor should be V series . Ask the vendor if it supports virtualization or not .If it doesnt , XP mode doesnt work in windows 7 .
Instead of Asking for Vista or Windows 7 , the question XP or windows 7 might had got more responses
Vista and windows 7 are more resource consuming than XP . ( Memory ,Paging ) . But Multimedia options are good in Windows7 .
For a cool user who do not want much clutter , Xp is the better choice.
