Lenovo Thinkpad Twist
2013 was the year when convertibles came into their own. They twisted, turned and tore to present themselves as tablet or notebooks as the need arose. The Thinkpad Twist was the best of the lot in our view as it is also a powerful device that could replace business computers. Other notable mentions are the Sony Vaio Duo II, Dell XPS 12 and the Acer Aspire R7.
