I don't see why these hardware manufacturers think they can just shit out handhelds and then call it a day. Valve spent so much time in R&D with steam os trying to make an actual usable mobile interface for the deck, and they've so far done an outstanding job doing that.

For example, on the deck if you run into an issue, say for example an app crashes. No problem, just press the home button and exit the game. Worst comes to worse you just restart steam (you can now restart steam instead of rebooting the entire device).

On a windows device, especially something like this, if your game crashe, unless the device has an overlay that allows you to force close the game you'd have to plug in a keyboard to alt tab. If the overlay app crashes then you'd absolutely need a keyboard.

There's just so many issues that can arise that will understandably piss off the user trying to use these devices to simply play games, but issues happen and windows is the absolute least mobile friendly OS to use on the market.

I feel like these manufacturers expect the hardware power alone to sell the device, but the secret to valve's success has mostly been with Steam OS and not necessarily the deck hardware itself.
