IE6, you'll be remembered for wasting hours of my client's time and money working on stylesheets specifically designed for you. You'll be remembered for never really delivering and of course your inability to deal with transparencies and your quirky ways with roll-overs.
Of course, we'll also remember you symbolic role as Microsoft's effort to marginalise other browsers by keeping you in the game for so long. Sadly, that backfired so you had to go. Long live Firefox and Safari!
