So as some of you know I have been playing with HTML5 on mobile for quite a while. And I have been experimenting with some libraries so far: http://jquerymobile.com/, http://jqtouch.com/ and http://www.sencha.com/products/touch/
My main goal is to make an application that has the same features as an iPhone and Android app: fast, rich ux, smooth transition, offline capable. It doesn't have to mimic a native app but the user doesn't to feel he misses something. Just as someone using Google Maps.
So for the Google Developer Days I've prototyped the agenda with Sencha Touch: http://touchium.com/s/gddde
Although some of main features are missing (offline, favorites …) what do you think? Is it better than the official mobile web site (http://bit.ly/gdddem)? Does it match a native client? Looking forward to your feedback.
