I think you'll find that every modern web browser can handle HTML5 perfectly fine
...
the results in their Gallery definitely don't work in Firefox 3.6.16....Safari no problem.... interesting
Right....
Except that in our universe the majority of users will not be able to see your HTMP5 creations in their browsers, while virtually everyone can see the Flash versions.
Plus, for complex animation Flash is way ahead of HTML5....
So I converted a 40K swf with this tool.
Ended up being a 400K file and didn't end up looking exactly like the swf file and plays soooooooo slowwwwwww on my iOS devices.
I don't get this anti flash thing.
Quite.
If you look at the demos provided, you'll see that the Flash versions use less CPU % than the HTML5 generated alternatives.
I don't think any browser currently uses hardware acceleration to render SVG.
From a user perspective, I find Flash > HTML5. Maybe that is probably because most browsers don't support HTML5 fully yet and when thy do, it will kick Flash's butt, but to this day I have yet to have a problem with Flash and I simply do not understand Apple's problem with it.
