Go to the library: File folders can now be organized into "libraries." You can have a photo library, for instance, that gives you quick access to pictures in folders spread out over your hard drive, or even several hard drives. This is great because many applications don't automatically put files into Microsoft's My Documents and My Photos folders.
Neat tricks: Windows 7 can sense if you use more than one finger on your touch pad or touch screen, allowing for neat tricks such as spreading your fingers to zoom into a picture, just like on the iPhone.
More speed: It's 64-bit operating system means computers will now be able to use a lot more Random Access Memory, or RAM, for better performance in demanding applications such as video editing.
