Safari was the first to pass the Acid 2 test, Firefox seems to have followed, and now IE8 is jumping on the bandwagon.
It’s good to see competition spur progress, and it’s even better to see competition on who can implement standards compliance faster/better. Hopefully this is a sign of even better things to come!
Someday developing web applications may not require so many browser specific hacks. Ok, maybe that day is a long way off, but I guy’s gotta have his dreams.
