At the time of writing, Lenovo offers three additional processor choices (i5-4300, i7-4500U, and i7-4600U) and a upgrade from a 128 GB SSD to a 256 GB SSD for $150 more. In the US, this lower-end, but still quite powerful version sells for $1299 directly from Lenovo. In this review, we will take a closer look at the ThinkPad Yoga, Lenovo's 12.5-inch business convertible with a Haswell 1.6 GHz Intel Core i5-4200U processor (3MB Cache, up to 2.60GHz), integrated HD 4400 graphics, 4 GB RAM, 128 GB SSD, and a FHD (1920 x 1080) IPS display. On the business end, customers so far had to contend with the rather unconventional 11.6-inch ThinkPad Helix, the single-hinge, more mainstream 12.5-inch convertible ThinkPad Twist, or the tried-and-true, but much thicker and heavier 12.5-inch ThinkPad X230T. Just last week we took a look at the new thinner, lighter, and more powerful successor in the consumer line, the IdeaPad Yoga 2 Pro with QHD+ resolution. The successful 360-flip convertible design Lenovo introduced with the IdeaPad Yoga 13 allows the new ThinkPad Yoga to convert from Ultrabook to tablet mode while still promising the performance and ergonomics of a standard clamshell notebook.

Lenovo's portfolio of Yoga devices keeps on growing.
