I am thoroughly impressed. Windows has brought glory back to it's name. Windows 7 is a much more powerful, faster and compatible operating system, outdoing its old counterpart XP. Windows 7 also provides the same aero glass theme with transparency and also a new wallpaper slideshow feature (similar [exactly the same] as Mac's OS X). This new version also provides a different style taskbar where only the icon of the running application appears, when hovering over the icon, the preview window appears, clicking on the window unminimises it or focuses it. This feature was a good idea at first and is quite fun, however, when in a rush, or trying to get work done quickly, it gets quite annoying. Compatability was something i was very impressed by. Windows 7 is slowly catching up to the Ubuntu method of drivers (you plug it in and it works). My printer, which has always caused driver problems in the past, just worked. I plugged it in and it downloaded and installed the drivers in under a minute. I was very pleased. One thing i am not happy about however, is they still have vista like security (windows asking permission very frequently, having to run some programs as admin etc).
Overall, a great improvement from Vista. On the M$ scale of 1/10, 10 being good, ill give it a 9.
