HP's adding more Leap Motion to its PC arsenal. After refreshing its Envy 17 with inbuilt Leap Motion control, HP's now expanding that partnership to select products in its desktop and all-in-one lines. The 11 devices, which encompass HP's Envy Recline, Phoenix and TouchSmart series, in addition to its Pavilion TouchSmart line, will come packed with the Leap Motion keyboard. But that keyboard would be useless without the necessary Leap Motion software, which HP's made sure to pre-install on the devices, along with a few free apps to demo the gesture control and Airspace, Leap Motion's own app store. If a motion-controlled PC sounds like something you'd want to gift wrap and nestle under the tree, then be sure to check out HP's online shop for the full list of supported devices. Because nothing says, "Merry Christmas!" (or "Happy Holidays," or whatever) like expensive, gimmicky technology.
