What's your idea of very little power, though?

I know for many who run SBCs (RK3588, Pi, etc.), very little is 1-2W idle, which is almost nothing (and doesn't even need a heatsink if you can stand some throttling from time to time).

Most of the Intel Mini PCs (which are about the same price, with a little more performance) idle at 4-6W, or more.

Not to mention there's more cost, effort, and energy effective compute from old laptops.

Unless you have a robot body for your potential RPi, don't buy one.

How?

I can fit a raspberry pi and external ssd in my pocket.

I cannot do that for a server.

I could use a laptop, but simply plugging in a firestick to the hotel tv or a projector when camping is nicer.
