TechReviewSource.com posted a review on the Dell XPS 12 hybrid ultrabook/tablet
The Windows 8 hybrid ultrabooks are here, transforming from laptop to tablet, and back again, with ease. The second of these shape-shifting laptops to come into PC Labs is the Dell XPS 12. As a convertible ultrabook, the Dell XPS 12 works as both a laptop and a tablet, utilizing the same flip-and-fold design last seen on the Dell Inspiron Duo (Black). Dell has dropped the Duo name, which is actually now used by Sony for its own convertible ultrabook, the Sony VAIO Duo 11 (D11213CX).Dell XPS 12 Review
The name change is understandable, as the XPS 12 has little in common with the Dell Inspiron Duo, save for the screen which flips around within a securely framed lid. The external styling bears a strong resemblance to the Dell Inspiron 13z, with a soft-touch exterior and metal frame. Looking at the specifications, it's clear that the XPS 12 is in a different category than the Dell Inspiron Duo, with an ultrabook-class Intel Core i7-3517U processor instead of a netbook-class Atom, and a 256GB solid-state drive offering significant performance gains over the slower hard drives used in netbooks.
