Putting the Windows 7 installation on a USB thumb drive has a few advantages—a small USB key is much more convenient for carrying around than a DVD, the OS will actually install much faster, and you can use a USB key to install Windows 7 on systems that do not have a DVD drive, such as a netbook. In fact, you can even install Windows 7 on netbooks that have fairly modest hardware.
