I don't play on the go either.  Usually streaming Xbox to my laptop or phone, or playing Diablo Immortal on my phone.

Now I'm playing PC games, steam games, PS3 and Xbox cloud in bed or iny lazy boy. Graphics are super impressive.

This morning I used chrome to get into my Citrix virtual machine and work for 30 minutes making changes to the enterprise mobility management system in bed on steam deck :D. Super awesome!!!

And yes, emulation of all old systems is amazing!  Some newer games have problems but otherwise it's been a power horse for what I've tried.
