Apple CEO Tim Cook once compared a tablet-laptop combo to mashing up a refrigerator with a toaster. The resulting Frankenstein device would do an equally lousy job of chilling your food and warming it up. That was three years ago.
Today, these tablet-laptop hybrids -- which blend the mobility and touchscreen friendliness of a tablet with the capabilities of a PC -- are on track to becoming the fastest-growing computing category. Shipments of so-called 2-in-1 devices like Microsoft's Surface Pro 3 and the Lenovo Yoga 3 Pro, for example, are expected to grow almost fivefold this year. That's thanks in part to attachable or foldable keyboards and more-powerful hardware, such as Intel's Core M microprocessors, that let slimmer, tabletlike devices hit speeds on par with midrange laptops.
