This is irrelevant to coding, but boy I miss what it felt like (as a child) to type on a T9 predictive keypad. Once you get used to it it's easy to 'know' by muscle memory when the desired word is the second or third choice, so you end up typing with basically the same number of keystrokes as qwerty but with only 10 keys.

Then again maybe this is only possible with the superpower of childhood cognition. I recently witnessed a friends 9yo playing with a 1940s typewriter I'd restored. Having basically never used a full sized keyboard before, within about 2 minutes she'd familiarized herself with the qwerty layout, figured out how to turn the shift lock on and off, deduced the correct key action to bounce the hammers off the platten without them clashing, and figured out how to change colours. All this took me at least 20 minutes.
