James Kendrick over at jkOnTheRun has had success in installing the Windows 7 public beta on the 10″ Intel Atom-based HP Mini 2140.
The Mini 2140 is HP’s “business” or “professional” netbook (the HP Mini 1000 is their consumer product).
Some have had an issue with Windows 7 drivers on the 2140. From the video, you can see that he has it up and running and that it booted up extremely fast.
