After years of fiddling around with Project Tango development hardware, Google has partnered with Lenovo to launch the first real consumer Tango device. This is the big day—the Lenovo Phab2 Pro is available for purchase. It's priced at $500, but it won't ship until December.

If you need a quick refresher, the Phab2 Pro is a massive 6.4-inch smartphone with a 1440p display, 4GB of RAM, and a Snapdragon 652 SoC. On the back are all the distance and orientation sensors that make the Tango augmented reality stuff work. Interestingly, the Phab2 Pro will launch with Android 6.0 Marshmallow instead of Nougat.

Google says there are more than 35 Tango apps ready for use on the Phab2 Pro. For example, you can measure things, put virtual furniture in your living room, explore the solar system, or play with dominoes. The Phab2 Pro is available only from Lenovo right now with a 4-5 week shipping delay.
