Nobody's specified the browser where CSS3 animations look bad yet. I'm not a web developer, but I use Safari, Chrome, and Firefox to varying degrees, and I don't see single-browser breakage going on.
True, unusued CPU power is "going to waste", but when an i7 950 overclocked to 3.5GHz, running of an SSD and 1600MHz memory with Chrome 18 uses 20% of CPU for a transition that's a problem (though with what is a different argument).
My point, though, was that to me it highlighted a more symptomatic issue, that a certain segment of the population, who used to rail against discrimination against their chosen platform, are more than happy to cheerlead / defend / exonerate discrimination for their chosen platform.
