RPi3 are reasonably capable for the price.=C2=A0 For me, t= hey make sense because:

This is probably an impossible question, but I've got to ask: Why do pe= ople even buy RasPis? Like, for anything? Even when the first RPi was new, = a second hand laptop could offer far more processing power and reliability = for the same price, sometimes excepting the disk of course. Add a base stat= ion with the old printer port and there's some GPIO; not as much as a R= Pi, it's true, but there are ways around that. One alternative for GPIO= is the actually cheap boards from Ti or whoever which exist to interface E= thernet, WiFi, Bluetooth, or USB on one side (depending on the board) to GP= IO and serial on the other. I think they're programmed in Forth, but I = wouldn't be surprised if you can just download programs for them to do = anything you'd want with remote control.
