Nice overview, Valve have been pushing Linux gaming for the better and the constant flow of updates have only made the Steam Deck better over the last few months. I think changes to fan speed and other variable screen refresh rate have made a big difference.
I'm a big fan of their approach towards self repair too!
I don't really see the deck as a direct competitor to the Switch, but definitely other x86 devices. Have you used the gyro at all?
