Same deal with the typewriter, tbh. It's always been one of the things that I want to buy if I get to have "a large amount of money." I used to have a fairly small one way back then, and it's small and portable enough to be stowed into some corner of my room when not in use, but it's a bit finicky to use. It's also one of those cheap ones that came out in the mid-90's, back when electric typewriters (and computers) started eating away at its niche.
As for the scooter, I think it'd be a lot more useful to me. I can use it for weekly errands (groceries and whatnot). For the leisure rides I really want it for though, I should probably want a beefier one (with more range etc.). Btw, what is an acoustic bike?
