Re: Pi vs PC
That doesn't hurt I'm sure, but depending on their goal, it's not quite enough. For education, you need some method of I/O, and most screens do need mains power. Even if it's one of the tiny HDMI screens that run off USB power, it's going to kill any battery you try to run it from. It's great when power is available but limited, but if you don't have consistent power at all, it's not well suited to it. Devices like a laptop which can run from an internal battery are better at that, but they're also a lot more expensive.
