Bottom line
Dell has revamped its rotating Duo laptop concept into the much-improved XPS 12, but like most convertibles, it makes a better laptop than tablet.
While there are certainly things to like about the Sony Vaio Duo 11, the design gets in the way of enjoying them.
Slightly less conservative-feeling than the average ThinkPad, the well-made ThinkPad Twist offers one of the better tablet modes from the first wave of Windows 8 convertibles.
