Well I went from XP 32-bit pro to vista home premium 64-bit a month ago. Mainly I wanted to upgrade to get full access to my 4GB of RAM and see how vista really was. I like it quite a bit, some people think UAC is annoying but I don't mind it at all seeing how it only adds one or two more clicks which takes 2 seconds to do. Not to mention all the other benefits of using vista. After using it for a month I can not see why everybody says they hate vista. I just feel like venting on this subject cause its rather annoying to me.
