I love typewriters because for me they're tangible, understandable, mechanical technology. Unlike an iPhone, or even a computer, I can wrap my bubble of a brain around how it works. I'm now the proud owner of 23 typewriters and can tell you stories, and anecdotes about each design, manufacturing, and origin.
It's strange how much fun it can be to spend an evening with a well-built mechanical tool, long forgotten by the rest of the world. I've got a portable ("laptop," LOL) Swissa Piccola machine that I just love, and a bigger 1937 Olympia whose keys feel fantastic.
