Its pretty clear that Lenovo made a mistake with its original Yoga laptop. Dont get us wrong, we liked — no, loved — it, but we could never get over how awkward it was to use in tablet mode: Every time you folded the screen over, you had your fingers pressed against the loose keys on the back. It was such a glaring oversight that even other companies have taken note: first Sony with its Flip line and now Toshiba with its 5-in-1 convertible that has a reversible keyboard.
