Anyone playing on Steam Deck/ low end gaming laptop?

Hi all, I have been playing on steam for a few years now. I have gotten a new job recently that requires me to work away for days on end. So I am looking for a second device to bring with me.

I am not sure if I should go for a handheld (steam deck/ lenovo legion go) or a lower end gaming PC. Anyone who currently plays on either of these? Can you share your experience/ pain points?

On a second note: what's the lowest end graphics card for the game to be playable? Would RTX 2050/3050/ 4050 suffice? Or go at least the 60s?
