i don't think i've ever ran out of ideas of things i wanted to do with a machine. i still have Commodore 64's Gary Kitchen's Game Maker project ideas, and i haven't messed with that in 20 years... i've always been on the software side of things perhaps, and besides doing too many different kinds of things at once which really require different, dedicated machines, i don't think i've ever used a machine to its fullest potential
