If you want a powerful full-size convertible with a 15-inch display and have less than$1000 to spend, the Yoga 500 15 must be on your list. It;s well built, includes powerful hardware, an excellent keyboard and a great display.
The erratic trackpad and average-at-best battery life might steer your towards something else though.well built and fairly nice looking, excellent display and keyboard, solid performance, runs cool and quiet, well priced.
