In personal, Windows Vista is a huge milestore for me--------the first beta operating system which I have used until RTM (from Beta 1 to RTM). The reason that I love it are the high-tec feeling and more user friendly GUI, for example, Windows XP don't have "Open With" function integrate into explorer, the only method is right click the mouse then select "Open With", which is very inconvenient for me, there are still many improvement which I cannot say within one or two sentences. The Aero theme and flip 3D feature make me amazed. Although many people say Windows Vista is a crap, slow, huge and high requirement operating system, I still love Windows Vista very much. For the system core, Vista has a lot of improvement and optimize, I can notice that when I switch to XP (My PC has two operating system installed). The world is getting improve everyday. XP is an old operating system and will can't catch up with the technology in a day. Windows Vista is a big milstore for operating system industry too, and the next generation of Microsoft Windows (Codename 7) will use the core of Vista and a optimized GUI from Vista too, I think the people who don't accept Vista better try to use it now.
