For me, it hits the perfect sweet spot. It's iPad-sized; there are no fans or vents; and I quite like the "Metro" touch apps because I'm already used to Windows Phone. At the same time the Clover Trail platform is fast enough to run Win32 desktop apps and the tablet comes with a pressure-sensitive Wacom pen, so it's a pretty great little machine for sketching and painting. I rather like the refreshed Office 2013 apps too, they're fine for mixed touch and pen input.
The Thinkpad Tablet 2 is also much less expensive than the Surface Pro, so I'm very happy with this choice... On the other hand I realize that my needs are those of a minority. The market for 10-inch Wacom tablets is presumably not that great. But if there is demand for "pro" tablets where precision input and access to the existing Windows x86 ecosystem are requirements, then Clover Trail + Windows 8 could have some legs.
