Most of my friends I know who went the kishi route instead of a stand alone emu handheld when I was rocking the rg355xxsp have since ditched it and acquired some manner of handheld, some even just opted for a legit GBA sp with a flashcart.

reasons I have heard:

Got tired of draining my battery
My phone doesn't have an SD slot and so I was not able/didn't want to load it with roms
it didn't fit in my pocket or was clumsy to use on the bus.

Your milage may vary. I still have a couple friends still just using their phone and they seem happy so take that as you will.

My kishi and s23uktra are my steam deck, Nintendo switch, emulator, rdp, note raking powerhouse.

I have a problem where the more devices I own. The less I use any of them. I'll spend my day just staring at them and then never commiting to playing them.
