I hate useless progress indicators, but it seems they're the most common type around. A progress indicator needs two things in order to be useful: knowledge of the completion time, even if only approximate, and consistent speed. I can't be the only person who gets ticked off at installers that go from 0 to 96% in 5 seconds and then spend two hours making up the remaining 4%. I'm not interested in how much work is left in the job, I'm interested in how much longer it's going to take to finish.
