Lenovo has made an interesting move to segment their Yoga 11 and Yoga 13 models. The Yoga 13 is an Ultrabook convertible proper while the Yoga 11 is going to be an ARM-based device that runs Windows RT. If the convertible Yoga 13 form-factor interests you, the Yoga 11 might be a desirable Ultrabook alternative for those looking for a more portable package with even longer battery life (and probably lower cost). Lenovo still hasn’t announced a release date or price for the Yoga 11 but full official specifications are now available. Photos on Lenovo’s website show what could be a micro SIM card slot for 3G/4G.
