Bought a 4k samsung in the local best buy yesterda

Bought a 4k samsung in the local best buy yesterday and I asked the salesman about the Nuvola NP-1. He had not heard of it so I explained it to him. He said he hoped Best Buy would hurry up and get that in because he said everyone looks at the 4k's but he has nothing to stream any 4k to the tvs on display. He also said if he had the Nuvola to stream and show customers the 4k tv's would be flying off the shelf.
