I wasnt the only one that thought Valve might be biting off more than it could chew, either.
The Steam Link and Steam Controller are essentially dead in the water now and never really took off.
The most interesting thing about the Steam Deck is that Valve says it isnt just a Steam Machine.

Valve
It isnt just a unit built to allow you to play video games from your Steam library.
Instead, its a full-fledged Linux PC that you’re free to install third-party software and applications on.
Shipping and Handling
It doesnt matter how promising new technology isor how cool it looks.

Valve
If you cant get your hands on it, whats the point?
This is another area where Valve seems to have learned its lesson.
Instead, itll just have additional components added in for some extra juice.
Of course, it also helps that thespecsof the rig look outstanding too.
