Hey Nitewalkr - sorry for being a bum and not responding to the other thread
. About the Lenovo tablet for ZB -- my boyfriend uses ZB and 3DC on his X220T (i7, 8GB ram) and while both work well, 3DC is pretty demanding on the hardware and temperatures fly (sometimes 90Celcius). But Zbrush is totally fine, and without lag. You just need to have an external keyboard if your screen is folded back. Sculptris is nice too, but same issue with the temperature. My bf also says Blender sculpting works smoothly and without any temperature issue.
If you want, since you're in 'Sauga, you are welcomed to come to downtown TO, to the former Alias office (King/Sherbourne) one of these days and give my X230T a spin.
I've tried the surface pro in the store and while i didn't get to use any real apps on it, i didn't really like the non-tactile keyboard and saw it more as an upgraded ipad.
