Typewriters are probably the most amazing thing on this list because most of it is just stuff we're stuck with due to lack of money/effort. They still make typewriters and they're not cheap. A new one is around couple hundred USD.

Another incredibly old thing people still use today is the old manual push mowers that just have 4 blades and no motor. Which is about the same prices of a push mower with a motor.

Personally, I just don't understand how there is a market for either product when there are so much better alternatives
