I said it in my post and I repeat it here: I truly love and believe in web technologies! I'm just saying they're still far behind native frameworks and that it's very hard (if not impossible) to reach the smoothness of native apps today, especially on mobile.
It's definitely possible to reach something "good enough" pretty quickly (made http://dribbble.deaxon.com in a few hours, check it on your iPhone) but I want people to be pragmatic and stop saying you can build the exact same apps with both technologies, because that's simply not true today.
I've been tweeting this today but I think it could be useful to repeat it here: my CSS demos are only experiments. The goal is to test all those new possibilities, show the power of CSS3 and, basically, having fun. They aren't intended to be used in production and actually you shouldn't. Most of them are not accessible and not cross browser…
