Apple Newton MessagePad
If you know what an Apple MessagePad is, you’re either a die-hard Cupertino fan or you were around when they were a thing. For everyone else, the MessagePad was a personal digital assistant (PDA) that first debuted back in 1993 — long before tablets or the digital assistants, such as Siri, that we know and love today.
The Newton MessagePad, for example, allowed users to take notes and send messages. While it looks pretty ancient by today’s standards, Newton MessagePads can still make you some money. This one, which is in good condition, is running for $1,249 on eBay.
