jQuery Mobile Alpha was released yesterday and it’s very good for an alpha. I think John Resig and team have a long way to go but the project itself is very ambitious. A full mobile framework for iOS, Android, Blackberry, webOS, MeeGo and more is nothing to sneeze at.
For example, after a few minutes on Android, I noticed that the persistent footer nav doesn’t always stick to the bottom of the screen. Since most mobile browser do not have css fixed positioning this ui paradigm is one of the hardest problems to solve. Notice that toolbars simply disappears on touch and reappear.
I look forward to the the next release, at the moment I wouldn’t say it’s ready for a production deploy. It is an alpha after all.
