Every writer should own a typewriter. There’s no other experience like it. Yes you have to learn how to clean it, but have you ever spent time in a poorly-ventilated room with an open bottle of mineral spirits? It's awesome.
Besides sorting through ideas, I like using typewriters to write stream of consciousness letters: I put a piece of paper into the machine, gather my thoughts, and then blast off. It's a chaotic, enjoyable mess. If you'd like one, please send your mailing address and three things about you to email@example.com.
Tom Hanks is the patron saint of typewriters; as such, it's his cosmic duty to commune with other souls committed to sending thoughts through antiquated technology. Here's some thoughts he sent me. Tom bless us all.
