The 2-in-1 and convertible PC space has changed significantly over the past couple of years. What was once a cluttered mess of kludges is now a well-defined market segment packed with refinement, power, and plenty of options. You could partially credit Microsoft's Surface line for making 2-in-1s an object of desire, but it's also products like the Dell XPS 12 that make today's line-up of convertible devices so much more interesting.

Dell's XPS 12, which was first announced last fall, is just as capable as a laptop as it is a tablet.
