Indeed. I was once engaged on a project to develop a new personal media player. QA had quite a selection of other vendors' PMPs, so we could learn from their mistakes: and ye gods and little fishes, poor UIs were abundant, not to mention often sluggish to respond.

(Sadly, ours never came to be, but that's a long and occasionally hilarious - in the DailyWTF sense - tale. Suffice to say, if your application crashes on trying to close any file, and the vendor's recommended workaround is to never close files, get ready for interesting times)
