Over a week of daily use, the Yoga 3 Pro never got more than warm to the touch. When I continuously played HD videos on it from a memory key, its 5,200mAh battery lasted for 6 hours and 49 minutes -- more than two hours longer than the Dell XPS 11's score of 4 hours and 35 minutes. With some judicious power management, this should translate into enough for a 13-hour trans-Pacific flight of on-and-off computing.
The system comes with Windows 8.1 Pro, a 30-day trial of McAfee Live Safe and Lenovo's Motion Control software, which lets you do things like advance a presentation's slides by waving at the webcam.
It comes with a one-year warranty that can be extended to three years for a reasonable $99.
Beautifully designed, the Core M-powered Yoga 3 should suit buyers in search of a top-shelf convertible. At $1,300, it's $250 more than a similarly equipped but thicker Yoga 2 Pro that doesn't last as long on battery.
If you have to have the latest in mobile technology and are willing to break the bank, Lenovo's thin, light and flexible Yoga 3 Pro has the best of everything.
