are you able to upgrade from win7 RC to win7 RTM?I know you couldn't upgrade from win7 beta to win7 RTM.
Now, how is win7 compared to win vista in terms of memory usage? Win7 task bar looks good but why did microsoft get rid of quick launch toolbar that vista had? Couldn't they keep it on if user wanted it? I seem to like that better than what win7 has with the quick luaunch and the program list on taskbar combined.
