I've been using Windows 7 in one form or another since the beta was released and I've found it to be very good. One of the feature you might want to explore is the Gadgets. These Gadgets sit on your desktop and provide weather, news, radio stations and other easy access to customize your desktop.
You can get to Gadgets by right-clicking on the desktop in any blank area and clicking "Gadgets." This will bring up a window where you can choose what gadgets you want to use. You can just click on the gadget you want and drag it off to the desktop. From there, you can move it any place you want. Most of them have options where you can modify the gadget. Just right-click on the gadget and select Options.
For example, you can change stations on the BBC Radio audio player. I usually listen to World Service. Try them all and see what's playing.
