Sure, if the budget is big enough, it makes sense to go to PrimeSense directly rather than messing around with Kinects.

Unfortunately the project I made was nothing like that. The client was a major Finnish multinational tech company (one that doesn't make phones), but their R&D is so backwards and completely oriented towards incremental improvements that this project had to be sneaked in through the marketing budget, using whatever crumbs of money they had left.
