This is good stuff. Would be great if it went right in and also talked about limitations like fewer ports-per-connection, poor standards support e.g. stuff like unsupported position:fixed property, dead file-input field, terrible response times for tap/long-tap etc.
I mean responsive layout for presentation of content (blog/BS) is fairly easy. For an interactive web-app however, design logic goes quite in the opposite direction. To this end I found http://html5rocks.com a very useful resource.
Looking at current number of devices and independent implementations of browsers having different levels of support for web standards, (even on iDevices!) I feel that we are sort of back to 1995.
