Lenovo’s first 11-inch Yoga device ran RT on an ARM-architecture. We ignored it. The second 11-incher was the 11S with Core CPU options. It’s still available with Haswell and a rather impressive power/battery life ratio. The latest Yoga 2 11 is more consumer focused and used the Baytrail-M platform. It’s a difficult one to position between an UltraMobile and an Ultrabook because on one hand it’s Baytrail (Pentium branded) and on the other it weights 2.9 pounds. It’s much like the new Sony Vaio FIT 11A flip.
