H.264 isn't exactly open, and Apple helped create it...what do you think will happen once they begin charging for royalties again? Apple is attempting to control how content is shared/distributed; if Flash dies, it benefits them, they want to be the MS of web content, just Google wants to the MS of web portals.
Competition is good, but blindly supporting one company over another is bad. None of these companies are your friends, there's money at stake, that's what they all want.
I have no problem with Flash; HW acceleration works great on my PC, while HTML5 videos may eventually catch on, it's not ready yet, and there's nothing standard or open about H.264, not to mention that there is no GPU acceleration for it yet in a browser. So you still need a beefy CPU in order to have something like HTML5 YT vids playback smoothly at full-screen. I'll have no problem with H.264/HTML5, once it actually matures and becomes viable, and supports GPU acceleration, but in the meantime, Flash is current and working now.
And Adobe just released a beta of Flash that supports the GPU's of some of the newer Nvidia GPU's in Safari and FF. After less than a week of the H.264 GPU API's being available...who was being lazy? Not Adobe, give them an inch, and they'll take it.
SJ sounds a whiny kid, and I wish he would just STFU already.
