This device is much less about phones, for me. I've never used mine with a phone. It's a type-c monitor with an integrated keyboard and pointing device. it's like a portable physical console in a laptop form factor. I carry it around and plug it into Raspberry Pis (via HDMI, not type-c alone) so I can get a physical console. I have a few smaller single board computers that I occasionally use it with as well. It folds completely backwards so you can use it as a monitor alone, if you want, and I do that with my MacBook so it's a 2nd monitor (or 3rd depending on where I am) and it's great. It's just a single type-c cable to give the Steam Deck a keyboard and a larger, higher resolution screen, for games that don't do well with controller inputs. Plug in a mouse, turn off the trackpad, and you're gold. This is far more than just a "turn your phone into a desktop" thing.
