watching Steam Deck reviews everyone agrees that the software needs some serious work. Hope Valve actually puts the work in. The Steam Controller got a lot better in the first half year but the promised(!) Bluetooth support only came years later when Steam Link became an app
that said I think the Deck will be a lot more successful than the SC (SC v2 with Deck input hardware when?) so 🤞
…and if it's not it's still a Linux computer so the community will make it awesome
