To partly alleviate concerns about the exposed keys, Lenovo sells a slot-in carrying sleeve that can cover either the whole unit or just the keyboard when it's in tablet mode. It's not a perfect solution, but it helps. Unfortunately, if you use the sleeve to cover the entire unit, the friction against the cladding on the outside of the Ultrabook makes it a little difficult to get the sleeve back off again.
At its core, the ThinkPad Yoga is a good machine with an appealing consumer-class feature set. Its rough-and-tumble approach to tablet and presentation modes might give some users pause. If you're looking for a convertible that doesn't sit on its keyboard, or more business/security features, check out the Dell XPS 12, the Samsung 700T, and the HP Revolve.
