The hardest part of this whole process might be deciding which handheld to keep!
Considerations: battery efficiency, screen size (I have 50-year-old eyes), and overall utility. We all know the Steam Deck OLED *should* win, but it's the smallest screen, and that makes a big difference to me now.
Surprisingly, the original Legion Go (with Bazzite obviously) might be my pick for the nomad life, due to screen size & detachable controllers. But you know me, I have to do some battery tests first.
