Last year the Lenovo Yoga 900 caught our attention as a high-quality convertible 13.3-inch ultrabook with an innovative 'watchband' hinge mechanism. The 12-inch Yoga 900s retains the watchband hinge and is generally very similar to its predecessor (including starting at the same £999.99 inc. VAT price), but is a smaller, slimmer and even lighter take on the ultrabook format.
