It’s the exact same Envy 17 that is on the market, with Haswell processors, NVIDIA graphics, HD touchscreen and Beats branding, but in this case, integration of the Leap Motion controller on the right side of the palm rest, with an app store built-in the Windows 8 build to give you access to the various apps the motion control can take advantage of.
Also, once you calibrate the sensor, you can turn the controller off by pressing the spacebar plus the Fn key; a small LED indicator will light up to let you know when it’s on. However, HP notes that the only real con of having it on is reduced battery life. Sigh.
Look for it October 16th, with a starting price of $1,049.99 and your choice of Intel Haswell processors and NVIDIA graphics.
