> No, RPis are very inexpensive computers.

This hasn't been true for 5 or 6 years and there is very little reason to buy one over a second hand 1L PC these days. They are expensive and notorious for screwing SD cards.

To put it into perspective, an 8GB raspberry pi with a 32GB SD card and cable but no monitor, no keyboard, no mouse is 251GBP. 35% the price of a macbook neo.
