Vista is a resource pig and is another ploy by Microsoft to extort more money from users!!! If PC's can run Vista they should have at minimum, 1 GIG RAM and secondly come installed with apps required by VISTA. Only Office 2007 will work on Vista which is another extortion by Microsoft. I work on PC's daily and do not see any great advantage of Vista. If I'm missing something please let me know. It runs extremely slow and too damn many questions...should I allow this app? blah, blah blah! I would install XP on this PC but I have users using Vista so I must keep current otherwise I'd be back on XP in a heartbeat!
