They lack the ecosystem and the army of developers to build it. Apple and Google are the best positioned at the moment with tvOS and Android but they're lacking vision. Samsung could enter the arena and then Huawei, LG, Sony, etc. I never thought about Dell, but since they rode the desktop/laptop wave they should invest in new technologies or undoubtedly face extinction. This is their last chance and stubbornness won't save them.
