The Lenovo Yoga 11S Ultrabook convertible is an 11.6-inch version of the Yoga 13, with one important difference — it’s running an Ivy Bridge ‘1.5’ processor, the Intel Core i7-3689Y.

We’ve got the Yoga 11S on hand and will be putting it through the paces over the next few weeks. For now we’ve got our initial impressions and photos for your perusal.
