What do you like about Windows 7?

People ask me if Windows 7 is any better. Sure. Some people are wondering about the security popups and compatibility with old programs. Those questions already have lots of press. But, I'm personally more interested in the small usability features that come in handy several times a day. Here are the ones I've noticed:

1. The entire organization of the task bar is a huge improvement. Basically the concept of Quick Links has been merged into the task bar functionality. (It acts more like OS X.) In previous versions of Windows, my task bar was always full of running programs, making the task bar difficult to use. Now my task bar stays about half full and my programs (quick links and running) are much easier to access.
   
2. Closely related to the previous, is the right click behavior on the task bar icons.
   
3. The Recent Document has been replaced. Now recent documents appear to the right of any program that is displayed on the Start's popup. So Word has its own recent documents. Excel has its own etc.
   
4. Snap is something I use regularly. You can drag an open application to the top or side of the workspace and it resizes to fill the screen or half of the screen as appropriate. Grabbing an application's border and dragging it towards the top resizes the application to the height of the workspace.

I notice these features several times a day. They are the main reason I like Windows 7.
