i still dont see how this is a bad idea
i would make 30 - 40 dollars a computer and it would take me like 3 hours to build it when all the parts arrive
since im thinking local at the moment i would only expect 2 orders a week at maximum
sounds like a good hobby and im making money while i do it
why are you designing a product before you know anything about the market/who you're selling to?
im marketing to anyone who wants to buy it
i dont really need to do age groups or anything
