intellix for your feedback. Surely Sencha making a framework like this with a free commercial license available is awesome. As jerome said
Sencha Touch is only in version 2.
and i am sure there is a lot progress happening at Sencha. Nevertheless the question seems how fast it will mature and if it is too early to rely on it at the moment. Having this in mind the following up question of course what cross-platform mobile development alternatives are out there which proves to be more mature. I am looking around for a while now and many of the frameworks available seem not to be mature either. Any suggestion?
