The black friday deal was ok. So I bought one and sold the original Xbox One a few days after.
Was it worth it? Not really.
It smaller, Almost as small as the WiiU (I have both side by side).
It loads and navigate the menu a little faster.
The power brick is built into the system.
It is quieter.
4K Bluray player. The cheapest 4K bluray player is more expensive than a Xbox One S.
HDR gaming and video.
So really... it is only worth it if you have a 4K/HDR TV.
