Windows 7 is great, possibly the best Windows yet

Prior to this year, I have never beta tested any operating systems, nor have I been an early adopter of a Windows operating system. That might all have to change now. I waited months to get this beta, since I began to hear about it in November of 2008. I am not in any way disappointed with the Windows 7 beta, build 7000.
The first thing that strikes me about the new OS, is the taskbar. This new taskbar is like a fusion of the windows Vista taskbar and the Mac OS dock. Instead of having launch icons and buttons for open programs, they are all one. Open a program from the taskbar and the icon lights up. No more tiny quicklaunch icons! The once eye candy window preview is now finally useful. Now that one taskbar icon can represent several windows (a browser window with a download window). Hover over the icon and the preview pops up then pick which window you want. Now you can unclutter your desktop by putting icons for you favorite programs in the taskbar. This does not mean that you should clutter your desktop with junk that you may download! (You should make a folder in My Documents for downloads).
Windows 7 makes it easy to use multiple monitiors, too. Press the Windows logo key and P and a small window pops up with a few options. One click you can change the configuration of your multiple monitor setup. Sure, it says projector but, thats probably what the majority of people operating a secondary display are using. All you have to do is set up your multi-monitor configuration once, then use this key combo when you want to turn enable or disable one of the monitors (for gaming or whatever).
So far I have installed two games under Windows 7. Using Steam, I installed Portal. Portal does not run nearly as smoothly as I like, most likely because of my graphics card and the high detail settings. The second game I installed, was Empire Earth. It seems to play just as well as when I run the game under XP. I have all settings turned to high and the resolution at 1680x1050.
This is about the extent to which I have used Windows 7, so I will report more on it later when I get to use it more extensively.
