Funny they mention Zynga... Remember Words With Friends? If you found a particular URL, going through x.facebook.com to play it, you got access to a HTML5 touch enabled version of it, with full cross platform play. I was using that to play it against my girlfriend at the time, on my Nokia N9(!) in 2011. It was all done with divs and funky JavaScript, and was amazingly solid.<p>Also, I'm really looking forward to Day[9]'s WebGL real time strategy game, I forget the name of it, but the technology is mind blowing. The difference between web code and native graphics is shrinking rapidly.
