The ThinkPad Helix, a slight variation on some of the convertible themes we've seen previously from Lenovo and other companies. Lenovo calls this clamshell a "rip and flip" design. That means the screen itself pops off from the keyboard base, as in a hybrid laptop/tablet, but then can reattach after being rotated 180 degrees, leaving the screen facing out from the back of the system (similar to the Dell XPS 12).
