The company is introducing the Lenovo X1 Thinkpad tablet, which features the newest Intel Core m7 processor. The X1 tablet also features a detachable Surface-like keyboard, LTE-Advanced connectivity, and, perhaps quite uniquely for a tablet, a detachable rear panel 'for serviceability and upgrades'. The ThinkPad X1 tablet will be available in February starting at $899, with the productivity module adding another $149 to your bill or $279 for the pico-projector.
