I've been using a Pi 5 to make the portable Folk gadget -> oh, I should add a battery system -> oh, I should add an accelerometer and speaker -> isn't this basically a smartphone? and yet there's still some gap where it would be very annoying (in different ways) to use an old Android phone, and nobody really does that in practice https://social.omar.website/@omar/statuses/01HTZFTDK6P0NC2QY7Z6ATR4M1
somehow solving the hardware problems of tacking all these components on is easier than solving the software problem of contorting Android to be a computer operating system instead of a smartphone platform
