It's not that slow. I know this because I've done it. You just need to use the HW accelerated transforms/animations. They're pretty easy to use, and documented. There are some undocumented css things which cause slow downs though.
Animation is as fast as lightning, with expert timing. In fact it's a little bit frighting what you can do with it. If you use js setTimer based animation it's not that great though. You need to use the css animation stuff really.
Audio can be played with no user action - again I know this from direct experience.
Only the small devices play video full screen (currently... I can't comment on upcoming IOS releases ;). The ipad can play them without going fullscreen.
You can't just use links, with click events. Understanding how touch input works with multiple fingers moving on the screen, not waiting for releases is different than understanding interfaces with a big screen and one accurate mouse pointer.
Expect to pay top £/$ for good iOS html5/css/js/svg/canvas developers that also have experience on iOS/android/nokia/palm... if you can find them.
Any idea where the market is for such developers? I intent to go the HTML app route, but I worry a little that I won't be able to get contracts for creating apps because I lack experience with the native side.
Hey, if you have a working example of two simultaneous audio clips playing in an iPad, run off a timer with no user click to initiate it, I'd absolutely love to see it and swipe the code. Ditto for smoothly panning and zooming a scene without the 'disappearies'.
That sort of thing is trivial in a browser, but it just falls down on apple devices. If you have counterexamples, you can save me a lot of grief, so please share them.
