PS4 and Xbox One have this as well. No one really cares.

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.

Every Playstation 3 and PS4 has had a decent browser. Not a killer app. Everyone would rather do all of this stuff on their phones.
