Moving from Sencha Touch for my mobile web app, where to?
We have developed a mobile web app in Sencha Touch and I am really disappointed with the end results - we have started 6 months ago, and now Sencha 2.0 is out, so there are loads of bugs in Sencha 1.2 which the Sencha team will not even fix anymore. 

When we took a decision to go with Sencha, we had looked at JQuery Mobile, but it was very slow on Android. Sencha Touch worked much smoother, but a couple of annoying bugs, slow turnaround and small developers base begs us to reconsider the technology. 

Questions:

1 - From your practical experience, what would be the best technology for mobile web development to go with?

2 - What technology do largest sites (Facebook, LinkedIn, Pinterest, etc.) use these days for their mobile web apps?

3 - Finally, should we just stick to HTML5+JS+CSS and bet that the mobile browsers will improve the support for those standards?
