4 years and 3 months still going strong. I use the touchpad a ton too and that coating on it has come off too, but it's perfectly usable. It also surprisingly lasted two pretty bad falls with just 1-2 minor cracks that I had to open the laptop up so that i can super glue the cracks just to ensure the cracks won't spread from future vibrations.

Visual condition is pretty unappealing, even a bit bad: the erased keycaps, the lifted coat off the touchpad and one visible crack, but it runs just as it did the day I got it
