Intel's latest IDF announcement should be welcomed by JavaScript developers: http://www.bit-tech.net/news/bits/2012/09/13/intel-river-trail/1
They may be "narrowing the gap". But while there's a gap there will always be a gap. Demanding software will always be written in a way that optimises performance. I think we're a VERY long way before top tier games and apps are written in javaScript and HTML. But maybe some clever development platform bods will create a framework that allows us devs to work in these higher level APIs and then optimise the code for each platform, offloading to external code etc as part of producing the application package. Interesting, but "Photoshop CS8 HTML 5.0" isn't going to happen (IMHO)
not true, doesnt Adobe offer a transcoder that takes flash and makes it into html5? Could have sworn they do because of Apple's anti-flash stance.
