Lenovo's Miix series sits in its Ideapad line, and so might not be a professional's first port of call when looking for a laptop. But these two-in-one laptop/tablet hybrids come in three sizes, and may well be worth checking out. The 12.2-inch Miix 510 is the mid-range offering, flanked by the 10-inch Miix 310 and the high-end 12-inch Miix 700.
