I'd disagree that the order of those is irrelevant. Far and away the two most important ones are `Price' and `Community Size'. If it cost three times as much,

I'd disagree that the order of those is irrelevant. Far and away the two most important ones are `Price' and `Community Size'. If it cost three times as much, the RPi wouldn't have been such a hit; if the community of users was tiny, it wouldn't matter how cheap it was because it wouldn't have critical mass. The Raspberry Pi managed to get out cheap enough and with enough support to make it a runaway success, which is why we now face a glut of similar machines.
