Now game devs can optimised their game for it and Steam Machine will get royal treatment. It's not unusual for a PS5 game to run slow on a PC with much better hardware due to not being optimised. The Nintendo switch is a great example, pretty old hardware but the games run well (for their intended experience).

Many people are complaining about the price but you can bring you entire steam game collection and even use as a PC if you want, I sold my PS5 once it became a useless brick cause Sony prevents you from running Linux.
