What better way to try Windows 7 then installing it on the Mini 9? Having read all the commentary about the smaller footprint of the new OS I couldn’t resist.
If you want to try this yourself, the procedure is exactly as if you were installing Vista. You will need the drivers folder from the Dell, along with the contents of the Program Files\Wireless Select Switch folder from the XP install and the R192569.exe file from the ZIPFILES folder which is on the support CD I believe.
