Dell XPS 12 convertible Ultrabook
Dell's XPS 12 convertible Ultrabook is an attempt to be all things to all people. By day, it can function as a standard office ultrabook, running Windows 8 in desktop mode and the usual range of productivity applications, with the added benefit of a touchscreen. By night, it can transform into a tablet-style device running the Windows Metro interface — and of course there's nothing stop you using it in tablet mode in the office, to deliver presentations or perform other business functions.
That's the idea, anyway. But does the combination really work? For the price of even the entry-level version of the XPS 12, you can buy a tablet and a laptop, so it really does have to meet both sets of needs well enough to justify the expense.
