The Lenovo ThinkPad X1 Tablet features a 12 inch, 2160 x 1440 pixel display, an Intel Core M Skylake processor, a USB Type-C port, and support for an optional keyboard dock and optional digital pen.
But what really makes this tablet unusual is its support for a series of modules that extend the capabilities of the tablet. You can increase the battery life, add a 3D camera, or  connect a projector by clicking one of those modules into place, as a Lenovo representative demonstrated for me:
Theoretically the modules don’t really do anything you couldn’t already do with a USB camera, HDMI projector, or external battery pack. But the modules are are bit more elegant of a solution, since they’re held firmly in place when connected, match the design of the tablet, and play well with the optional backlit keyboard dock, which can connect to the modules rather than the tablet itself when you’re using the tablet with one of its accessories.
Is that enough to justify the price tags? Umm… maybe?
The Projector Module sells for $279, which isn’t a ridiculous price for a pico projector… but which may be a bit much to spend on one that’s designed for use with a specific computer. The 3D Imaging module with an Intel RealSense camera is priced at $149, and so is the Productivity Module with a spare battery (for up to 5 hours of extra run time) and a USB 3.0 and HDMI port.
The tablet itself should be available in February for $899 and up.
