Windows 2007?? do you mean Win7? Anyways it is what Vista was supposed to be a whole year before it was even released. So whilst sure its their best OS to date, its been a long time in the making and took an awful lot of PAYING beta testers to work this out.. Thats all Vista was, win7 beta.. and look at all the people that paid for it.. if it was a Linux distro it would have been classed beta or end in an odd number release (same thing mostly) and supplied free of charge.
