I lowkey wish Nintendo would rerelease the GBC or GBA I would buy one. They can bake in some games into a few cartridges and make it 100% worth the buy too.
I've still got my Gameboy collection, but rarely use it. It's just so much easier to fire up an emulator these days.

I went with getting a GBA SP and replacing the screen with a more modern panel. The kids love it.
