The other thing I miss about DOS is "typeahead". It used to work. There was basically one keyboard and one "window" and they were connected by a FIFO buffer.

Nowadays there are hundreds of layers of object between you and the guts of the API (including animated simulated layers of transparency) and many of those objects might not even exist in the right state until the last moment so those extra keystrokes go to the wrong place, or nowhere. Which means you often have to wait after keystrokes before continuing to do something.

Another reason why DOS often seems really fast compared to modern computers.
