>>3078Unless you're just wanting to game on something that looks like a glorified digivice (which with a touchscreen, should be out of the question) you really won't need anything more powerful than the zero. If you're wanting to stuff a GSM board and other related components in there, the zero will most certainly be able to handle that as well. We've gotten to the point with our computers that the only reason you would need a CPU faster than budget hardware is if you want to play modern games or you're doing super sciency Big Data™ things. Unless that applies to you, any of the Pis should be fine.
