Apple has used a tiny fraction of the 147 Billion they have on hand. They have supposedly bought the company PrimeSense for 345 million, which helped build the original Kinect for Xbox 360. This also adds even more fuel to the fire that Apple is working on an Apple TV, as we have written about on numerous occasions.
Who knows, these technologies may even make their way into iPads or iPhones under the right circumstances. This is another calculated purchase by Apple which tends to integrate the technologies of companies they purchase into products further down the pipeline. We saw this with SIRI and now Touch ID.
Who should Apple acquire next?
