IE9 is a dinosaur? Loads of locked-down corporate intranets still run IE6.
(For clarity, I wouldn't normally describe a two-year-old browser as "a dinosaur," mainly because the 5-year-old inside me thinks dinosaurs are too cool to use their species as a pejorative. But I would describe one like IE 9 as "fairly outdated," which is just a less goofy way of saying the same thing.)
IE6 is pond scum.
