Rubbish! Most moderately advanced HTML5 demos run hideously, if at all, on mobile hardware. The difference will be if HTML5 can replace 80% of Flash uses in a performant manner. The video tag makes up a huge block of that 80%. The other 20% will always run like a dog on mobile hardware, no matter the technology.

Always?! Even on mobile hardware that will come in 5-10 years?

Have you watched the Apple HTML5 demos on an iPad? It's actually revolutionary to see what they can do with the limited hardware. Being able to touch and drag a 3d model around at 30 fps without stuttering? I can't even do that on a lot of PCs with Flash.

  Here ya go. Give this a try and let us know how it runs. http://xplsv.com/prods/demos/xplsv_orsotheysay/ http://xplsv.com/prods/demos/xplsv_orsotheysay/

    I ran two three minute tests, one in Safari and the other Firefox on a 2.8GHz C2D w/ 4GB RAM and nothing else really open. In Safari 5.0.1 your link didn't render a single frame in three minutes. Firefox 4b3 did render, but the animation would not normally be watchable. The opening scene ran the best, probably around 15fps while during second and third scenes the galaxies would jump about an inch with each frame. I don't know what the fps were, but it was updating the screen less than one time per second with a single core maxed out. Also, on launch, FF was using 76MB of RAM yet after the three minute test it was using 168MB of RAM. So your link didn't function in one browser, used 2.8GHz of processing power and ~90MB of RAM in another yet was completely unwatchable. Was I supposed to be impressed?

      It runs great in Chrome.

        Flash content runs in every browser.

      Well, the demo is an amazing demonstration of HTML 5, and the limitations of HTML 5...if your browser can swing it. It runs pretty great in Chrome, not so great in FF and sucks everywhere else. What if this were a Flash demo? Only be mildy interesting -- and that's only for the presentation itself. From a technology perspective it'd be ho-hum. I think more important than that is that it's not even interactive. Interactivity with HTML 5 apps has light years to go compared with Flash even if browser vendors can lick the performance problem. In other words, HTML 5 as a content delivery platform has a very long way to go...and as it is is certainly not anywhere near as a cross platform as Flash is. It's just not a swap out substitution for Flash yet and forces developers to produce software that's just simply not of the same quality as Flash is able to handle.

    I've got a quad core Win7 box with 4gb of RAM and a video card that runs Fallout3 at max settings on my 23" monitor without even noticing. Or So They Say only advanced frames in Firefox when I moved my mouse. It actually ran for me in Chrome, but was pixelated (2x?), and still laggy (I'm guessing <24fps) While it's cooler than anything I've ever done with javascript, I was watching more impressive demos on a Pentium 75 over a decade ago. HTML5/Javascript/etc. appear to have a long way to go, performance-wise, before they catch up to Flash. And by the time it catches up to Flash 10, where will Flash be?

    I noted everyone saying it was crashing their browser / etc.., but it worked perfectly on my computer (dual core, cheap video card, Chrome).

    That's a beautiful demo and it runs well on Opera 10.60/Vista.

  This page: http://www.apple.com/html5/ http://www.apple.com/html5/ ? The 360 there is a simple pre-rendered jpg sequence. But I'm hoping you're referring to a real-time 3D execution. If, please share a link.

Then can you explain why setting font size to 200 on this HTML5 demo http://www.ponticstar.com/projects/burning-words/ http://www.ponticstar.com/projects/burning-words/ then my browser is slowing down to unusable? I've seen burning words demo in Flash 4 from 2000 and it's very smooth even on a PIII machine.

    Without examining the code it's hard to jump to conclusions, was the flash version really rendering the effect pixel by pixel as I'd imagine the HTML5 one is?

    Opera 10.61 still works well with that 200 font size. It has however one core maxed out.
