Lenovo ThinkPad Helix
Lenovo used CES 2013 to debut another new convertible PC called the ThinkPad Helix Ultrabook.
The super-thin laptop can be used as either a traditional notebook or as a stand-alone tablet by detaching the 11.6-inch display. It includes a unique hinging system that, like the new IdeaPad Yoga 11S, lets it take on a third form factor called stand mode.
Lenovo said the device will start shipping in late February, starting at $1,499.
