I think you're so so lazy! You should have put out 15 software updates by now!
But more seriously, I see where you're coming from, but I think they have more on their plate than you may think. Slow? Eh maybe, but lazy? I wouldn't be so quick to judge.
Also remember that carriers are often huge bottleneck and that they are maintaining multiple models.
