LG is offering its own take on the Windows 8 convertible in the Tab-Book. The Tab-Book is a tablet/notebook hybrid that LG says is ideal for users on the go. The Tab-Book includes built-in LTE for mobile professionals, who'll have access to 4G for speedy mobile broadband. It is powered by an Intel Core i5 processor and has an in-plane switching LCD panel for a wide viewing angle and natural color. LG hasn't shared all the details about this device yet, however -- we don't know how big the screen is, nor do we know specs such as battery, camera, size/weight, and more. LG is planning to reveal the full Tab-Book story in Barcelona.
