You would go for a Raspberry Pi when you need something it was invented for.
Putting a computer on your motorcycle or robot or solar powered RV. Super small space or low-low power availability things, or direct GPIO control.
A MiniMicro will run laps around a Pi for general compute, but you can’t run it off a cell phone battery pack. People only related Pis to general compute because of the push to sell them as affordable school computers, not because they were awesome at it, because they were cheap and just barely enough.
Sorry, no touchpads, no real interest from me.
I need a Steam Controller 2 with the same controls as the deck itself, so I can configure and learn one layout, not enjoy the virtual menus or trackpad mouse control on one and then go without on a basic Xbox layout in another.
