The first phase of that transition is already under way - Windows 8 hybrid systems show a little of what's
possible. Lenovo's Yoga 13, Dell's XPS Convertible Touch, and the Sony Duo 11 are already combining
elements of tablets and laptops. But these systems remain more laptops than tablets overall. The Sony Duo 11,
with its 11-inch screen, is the lightest of the bunch, yet it still weighs nearly 3 pounds. Today's pure tablets have
smaller screens and limited storage, and lack the performance of full-fledged laptops.
