When was the last time you saw a convertible ultrabook? I really do not remember, but I'm pretty sure we've seen some before. The model we see on screen today is Dell's new creation, and has been dubbed Duo Dell XPS 12. What makes this ultrabook is different from the others? Well obviously that can be used as a laptop or a tablet, and it has a touch screen of 12 inch Full HD (1920 x 01080 pixels).
But the screen is not the only good...
