Mac OS or Windows 7 or Windows Vista Black Edition 2009? -

i ve downloaded Windows 7 Beta [7000.0.081212-1400_client_en-us_Ultimat... And I want to Know whether Windows Vista Black Edition 2009 will be good or this one copy of Windows 7 I also Want to Know about the advantages and Disadvantages of Mac OS, Windows Vista 2009 (Black Edition), and Windows 7 Beta release...

Better stick with Vista since Windows 7 is still in it s beta stage. But if youi re the type who wants to test the new OS, provide feedbacks, then Windows 7 would be your choice. Btw, there s no black edition for Windows Vista. i m assuming that is a customized version of Vista .. be careful though in installing those customized OS .. there s always a possibility that the person who made that injected a backdoor program or something. stick with the original OS ;)
