I acquired one of the Lenovo Tablet 2's (64GB SSD / 2GB ram) as a test device in my prior job. I also had a chance to play with the newer Tablet 10 (with digitizer) just before I left there.
The device itself was just fine for what it is, but even the Z37xx series Atom was still not fast enough to reliably keep a good polling rate on the digitizer interface. The cursor underneath would "lag" behind the physical placement of the pen on the screen with moderate speeds; fast handwriting was not always a great experience. Also, the little digitizer pen was
little, it wasn't always comfortable for my hands -- and I do not have big (by men's standards) hands.
Still, one of the things they got right was the placement, and (at the time) they also got the thin and light right against the Surface Pro 2. The Pro 3 solved that problem, but at a much higher price tag. Now that the Surface 3 is out, I cannot fathom the Lenovo Tablet 10 surviving much longer.
Right before I left the last employer, we bought both a MBP 15" and also picked up a 30-day loaner SP3 i5 8GB/256GB package with type cover from our contact at CDW. That SP3 was sexy as hell, carried well, lasted a long time, "all the things."
After I left, they gave back the SP3 i5 and bought five of the i7 8GB/256GB models with the type cover. Jealous
