The Envy 17 with Leap Motion features a 17.3-inch display with a 1920 x 1080 resolution, a fourth generation Intel Core i-series CPU, Nvidia graphics (though HP is keeping quiet on the specific GPU), 8 GB RAM and a 1 TB HDD (the default drive is 5400 RPM, but you can pay more for an upgrade to a 7200 RPM drive). Of course, the big thing about this machine is that it has Leap Motion's sensor built in. This means the Envy 17 can detect motion from two hands or 10 fingers so you can navigate and control your computer during games, presentations, etc., without using the keyboard.
Users can download Leap Motion-compatible apps from Leap Motion's Airspace Store, which currently only has 100 apps. That said, as more companies integrate the technology into laptops (Asus is apparently partnering with Leap Motion, too), and more people buy the standalone sensor, that number should rise.
The Envy 17 Leap Motion Special Edition will be available October 16 starting at $1,049.99.
