PC manufacturers seem convinced that everyone wants a Windows tablet, be it 8 inches or big enough to double as a TV tray. The larger models are effectively all-in-one PCs that can lie flat to allow several people to interact with the touchscreen at once.
Lenovo scored a 4-star win with its 27-inch Horizon. The Flex 20, which the company describes as a "dual-mode desktop," is smaller, lighter, and less expensive than the Horizon, addressing two of the complaints we lodged against that machine. Regrettably, in the Flex 20 those advantages come at the cost of performance and resolution, two shortcomings that pretty much ruin the table-gaming experience.
The Flex 20's specs read more like those of a bargain-basement cheapie than of a machine you'd expect to play games on. Powering the Flex 20 are a dual-core fourth-generation Intel Core i3-4010U processor, integrated Intel HD 4400 Graphics, just 4GB of DDR3/1600 memory, and a 500GB mechanical hard drive that spins its platters at 5400 rpm. The saddest spec of all is the screen resolution of 1600 by 900 pixels—a 19.5-inch IPS display needs 1080p.
The performance is what you'd expect of a machine with such specs. The Flex 20 managed to post a WorldBench 8.1 score of just 78. That's 22 percent slower than the benchmark results of our reference all-in-one desktop, an Acer Aspire U A5600U-UB13 powered by a third-gen Intel Core i5-3230M. The 27-inch Horizon, meanwhile, delivered a WorldBench 8.1 score of 111. And Dell's XPS 18 Touch—another all-in-one tablet/hybrid—scored an impressive 171 (with the assistance of its 32GB SSD cache drive).
What does that mean for family game night? A lot of waiting. Lenovo created a custom interface called Aura, designing it in a ring so that users can control the tablet from any side of the screen. Launching a game in Aura left me on a blank screen long enough for me to start wondering whether the game was actually launching or if the whole thing had crashed (which it did, on occasion).
Battery life is adequate for a quick evening of gaming. The Flex 20 lasted 3 hours, 25 minutes playing high-def video in our run-down tests, which means the kids could grab it for movie night—and considering that it's just 7.7 pounds, they could probably get it to their room without your help. Gaming will eat that up a little faster: In our tests, 2 hours of play left the battery with a 25 percent reserve.
Lenovo offers some interesting wireless accessories to enhance the Flex 20's gaming capabilities: joysticks (which attach to the touchscreen with suction cups), air-hockey strikers (small paddles that glide over the touchscreen), and the E-Dice (a die that tells the computer which side is up after a roll). Unlike with the Horizon, you must purchase the Flex 20 accessories separately: A package with one pair of joysticks and one pair of strikers costs $50, and the E-Dice costs $60. A wireless mouse and keyboard are included with the PC.
