Dell XPS 12 Review: convertible Ultrabook
 

A couple years ago Dell released the Inspiron Duo. It featured an innovative, rotating touchscreen. It was a very interesting design, but the Atom processor it ran on was too slow. Fast-forward two years, and now Dell has come with the XPS Duo. Again called Duo, it applies the same concept: a screen mounted in the middle of a frame, which you can spin around. That enables you to use it either as a laptop or as a tablet. While its exterior does resemble the Inspiron Duo, the hardware is fortunately much better in every regard.
