Someone has decided to install Windows 7 on a Ultra Mobil PC (UMPC) with only a 600 MHZ Atom processor and 512 MB of RAM. This machine comes with Windows XP and from my personal experience can barely handle it. The amazing part is to see just how responsive the machine is when running Windows 7.

The Windows 7 Engineering team has posted to their blog some additional details concerning Windows 7′s Windows Experience Index (WEI) and the changes that have been made since Vista.
