Speaking of phones, here's one I actually own and still use occasionally as a backup device, since it's perfect for that job!
The Nokia 1100 is apparently the most successful phone ever(?) and it's built to last. It's a very basic phone even for its time, but it has a neat dust-proof keypad and it's the first phone with a built-in keypad! It also comes with Snake 2 and an editor for ringtones, but mine doesn't play ringtones for some reason so I couldn't try that.
