Intel sells the RealSense Developer Kit Camera for $99. It is meant for developers only and produced in small batches when enough orders pile up. As a consequence, you may have to wait a while for yours.

If you are looking for a new Windows laptop or desktop, there are already a few with integrated RealSense cameras:

• Dell's 2015 Inspiron 5000 laptops and Inspiron 23 All-in-One desktop PCs.
• The HP ENVY - 15t Touch laptop.
• Asus' N551JQ notebook and G771JM ultrabook.
• Acer's Aspire V17 Nitro gaming laptop.
• Lenovo's 2015 Yoga tablets and laptops.

Also of note is HP's Sprout. Its "HP Illuminator" device with built-in RealSense camera is oriented toward the desk rather than the user, so it will probably not work for head position and expression tracking, but there is also an ordinary, user-facing webcam which may be usable.
