Computers are, as a rule, a train wreck when it comes to usability and user experience. Like I'm trying to install something on the command line in a terminal program, and it does some escape code trickery to show a running tally of "bytes downloaded / bytes required (complete%)", and in doing so prevents me (apparently) from using the mouse to click-drag-select text. I guess the cursor being updated like that screws it all up. So that's freaking genius!
