While the T430u isn't a radical departure, the ThinkPad Hybrid X1 is definitely something different. This 13.3" ultraportable is less than 0.6" thick, but it manages to squeeze two processors into its slender chassis. The first is your choice of Core i3, i5, and i7 CPUs, while the second is a dual-core Qualcomm chip based on the ARM architecture.

That Qualcomm chip gets 16GB of dedicated storage and a "custom Linux-based operating system" capable of handling media playback, picture browsing, and web surfing. Users are supposed to be able to switch between the Hybrid's processors with the touch of a button, and both run off the same battery. Incidentally, Lenovo claims that battery can be charged to 80% capacity in only 30 minutes.
