"Most browsers have hardware accelerated rendering of 2d canvases."

Actually, you'd be surprised. For most users all the rendering is done on the CPU. The major exceptions are IE and Firefox (with non-blacklisted drivers) on Windows Vista or newer.

Huh? Both Safari and Chrome support hardware acceleration of 2D canvas.

You're probably right. I was under the impression that Chrome wasn't shipping Skia GL on desktop yet, but my info could be way out of date; I haven't checked recently.
