Surprisingly Nvidia has done something rather innovative with its latest Vista drivers, and the Go5200 now uses shared memory. Which means it can take a chunk of the tablet's 1GB of RAM, and bootstrap itself up into using Vista's high-end graphics modes.
A nifty hack.
The combination of Vista's search-based UI, Aero Glass, and the M400 Toshiba driver hack (and now the 2007 Office Beta 2 Technical Refresh) have given a nearly three year old laptop a new lease of life.
I still want a Core Duo Toshiba M400, though...
