Most reviews summarize that this is an ultrabook convertible more suited for business, not entertainment. Either way, the price is considerably less than most ultrabook convertibles.
Summary from the ZDNet review:
"If you think of it as primarily an ultrabook, but one that can conveniently turn into a tablet when the occasion demands, then the ThinkPad Twist has a lot to recommend it. The build quality is very good, and there are enough business-friendly features to make it acceptable as a BYOD system... Battery life may be a more general issue though."
Also note that if your tax is roughly 6.5%, then an alternative is to purchase from Amazon.com ($799.99):
Some benefits of Staples are you can try it out in-store (if in-stock), ship-to-store and maybe return it to the store...
