On a slightly related note, I am highly disappointed with the Spectrum boxes and really miss my Comcast X1 box.
Spectrum and Comcast both rely on the same third-parties to supply their gear but Comcast works with partners like Arris to build their own custom boxes. They have their own custom OS running on the box. They're really fast and have a very modern UI. For instance it'll open sidebars to show current sports games with realtime scores. They also have their voice remote feature which, at first was a total gimmick to me, but ultimately became really helpful. You rarely know what channel # you want but to say "go to TLC" or "go to the world series" is really handy. They also have a remote control with an accelerometer that will glow when it jiggles, unlike any competitor. This is very useful at night.
Meanwhile my Spectrum box is virtually a thin client. For things like on-demand it's piping commands across the network to a remote host that is rendering what is displayed on your screen. The latency is horrible.
I've cut the cord once or twice with services like Playstation TV and Sling... but none of them really shake a stick to a proper cable plan. I'm disappointed with this price hike and Spectrum's hardware but for folks (my wife and I) who grew up in the generation of cable TV it's a difficult habit to break.
