Some time ago we had discussion on why real player sucks so much. There were various points quoted. But the quote on IRC neatly sums our hour long discussion.
<mrm> i hate realplayer
<lummie> its good for cartoons
<mrm> but it crawls deep into the anus of my computer
<mrm> and hides there eternally
<mrm> until i least expect it
<JtHM> your computer has an anus?!
<Fesh> realplayer installs it
