Got a refurbished Latitude ST tablet on very reduced sale (< $300) from Dell to try out Windows 8 on touch hardware. I'll now grant that a lot of the decisions they made make sense in that context, although demoting the desktop to a second-class citizen makes no sense for power users, and the hacks involved in running the desktop as primary are a PITA.
It is, however, still not as good a tablet OS as Android or the iOS, and they have a high bar to catch up.
As an aside, the Latitude ST is the slowest machine relative to its current generation of software that I've used since abandoning floppy disks, and the slowest windows machine (in absolute terms) that I've used since 2002.
I can't recommend it for any purpose, and it's probably going back to Dell.
That said Windows 8 is much faster than the Windows 7 on it; it came out of the box with Aero, and everying crawled...
