I dunno, as a kid if there was a $40 or a $80 thing, I would get the $40 one (both would involve negotiating with parents anyways, and there's an obvious big gap here).

$40 is a lot of money for teens without income (which is the case for most teenagers across the world outside of the US). Most kids get money maybe once or twice a year and have to spread it out, and then negotiate for other hobby-based purchases when they can. There's a reason forums are filled with people discussing how to maintain sub-$100 Thinkpads!
