The Sony Vaio Flip 13 has the cleanest and most unusual hinge design we've ever seen. The display portion's aluminum back panel has a visible split and this is where the machine does its transformation from laptop to presentation mode to tablet. It's a better design than the Lenovo Yoga 13 and Yoga 2 Pro whose keyboards face down to rest on the table or your legs in presentation and tablet modes. At 2.89 lbs. the Flip 13 is also bearable to use as a tablet. The Vaio Flip runs on 4th generation Intel Haswell Core CPUs with 4 to 8 gigs of RAM and SSD drives. It has a lovely full HD Triluminos IPS display with wide color gamut and and an N-Trig active digitizer for digital pen. Better yet, it's also available in 14 and 15 inch models too. Is it perfect? Not quite, but it's definitely one of the best Windows 8 convertible designs on the market.
