Since I had the last good XP installation still remember, I noticed when loading of 7 immediately first advantages: Installation done almost completely by itself the beginning, enter a few names, at the end of the Product Key, do the rest. Win7 independently. This also applies to all drivers: Wi-Fi, 24-inch screen, sound, everything already there, no CDs more 'great!
The user interface came from my Vista-times yet known, but a thousand times User survey by Micorsoft proves to me effect. Because mouse and keyboard can many great things that are really fun and greatly enhance the work. Especially good: the Windows key-figures-key combinations that you can select the tasks in the task bar by chronological order. With Win key number + Win key cursor you can see the window then slide to the left or right of the screen, where they automatically take half the screen or to the top of the screen, where they can be maximized. So (or the mouse) I, for example, with just four buttons Printing two windows side by side Arrange 'super!
My Windows 7 Conclusion: The Mouse and keyboard, thanks to touch-screen support, very versatile. Win 7 can be highly individualized, eg photo-slide show as your desktop background. Of course me as a widget fan enjoy the numerous Windows Gadgets very well that you have all afloat on the desktop. I like the transition already, Win 7 is fun. Happy new year!
