The worst was the loading screen on the Spectrum. You never knew if it was just taking a while or if it had crashed. Often you'd wait 5 to 10 mins and just start again, sometimes you'd hit reset just as the game finished loading!<br><br>I quite like the way Ubuntu software update handles things by giving you the option to see a console output on what is happening behind that progress bar so you can see if it's stuck on something or just doing a lot of operations. In a way, progress bars have gotten more frustrating these days the more OS makers have tried to hide things away from users in the name of "user friendliness" when doing that is actually the opposite.
