I’m glad that Linux is getting backing from a huge company in this way. However, at its core the steam deck is a Linux based device with a heavily tailored UI running on known hardware with 1st party drivers. Consumers have been using Linux in this way for years without realising it. Sure, this one gives you far more control than you normally get but (in my opinion) the problems with Linux desktop come from support for a wide range of scenarios and peripherals. That hasn’t improved enough for me to switch last time I tried.
