Definitely quite expensive, but very impressive. Assuming no tricks were being played, the auto-hover demo video is quite cool. The unit was autonomously correcting both its altitude and attitude, in response to fairly severe upsets for a device of that weight. With less success, it was also correcting its position. Neat. If the application is aerial photography, sensing, surveillance, etc., such autonomy would be a major workload reducer, and make it practical for one person to handle both the flying and the shooting.

Knowing little about the technologies involved, I'm not surprised to hear it stated that the advantage of TI is low cost. The TI technology is still an ingenious and novel approach to solving the problem, though. Obviously, a unit equipped with sufficient gyros and accelerometers should be able to accomplish altitude and attitude hold without sensing a horizon (and TI only accomplishes the latter)...but those costs remain high. They will come down, though!

Now I want a MicroDrone, to add to my growing stable of four rotor 'copters. But there's no way I can justify the cost, unfortunately.
