The Leap Airspace store features a nice collection of apps, which enable everything from Minority Report-style gesture controls to music creation to mid-air painting. According to HP, pricing for the Envy17 Leap Motion Special Edition will start at $1,049.99 with a Haswell processor, 8GB of RAM, and a 1TB 5,400-RPM mechanical hard drive. You'll be able to throw in a second hard drive (or, presumably, an SSD) and add discrete Nvidia graphics. The press release also mentions a "17.3-inch diagonal optional full HD display," which likely means the default resolution will be less than 1080p—but you'll be able to upgrade.
Leap Motion will also be bundled with ASUS high-end laptops and All-in-One PCs, but while HP chose to integrate it into the system, ASUS decided to bundle it as a seperate peripheral.
