Many years ago I used a TUI retail/inventory terminal that was running in an SSH session over a painfully slow wireless link. Each keystroke came with several seconds of latency. This was not a problem, though, since I'd memorized all the important menu sequences. I could just punch in a rapid-fire string of keyboard strokes representing an entire transaction and then just wait a few moments for the screens to catch up and a receipt to print.

I think this is one of the deepest problems with modern UIs - event delivery is no longer reliable. You type "abc" and only "ac" gets delivered to the application, or "b" ends up sent to another window. Maddening.

I do this to this day, over a crappy kilobyte line via Phone via Bluetooth and it works great.
