Which is bad for developer centric product design but what about user centric product design? Honestly feel like I'm back in the IE era at times as I go over to devs and point out something isn't working only to be told "try it in Chrome". Only difference between the IE era and the Chrome era is the self satisfied grin that they're on the cutting edge when something only works in Chrome.
