Well, I've tried out AppMobi a little bit.
1. Created a AppMobi sample project
2. Exported as AppMobi experimental directly into the Appmobi project directory, looked okay in XDK viewer
3. Built as a distributed webapp
4. Copied into my dropbox folder for testing.
My results were.... mixed to say the least.
Sound seems to work a little better, and everything works with my ipad 1st gen as well as an ipod touch. Downside, is that it doesn't view in firefox properly, three question marks show up and nothing loads at all. Chrome loads the game but the Touch plugin with mouse control is oddly disabled.
F5 Preview works on both browsers perfectly, and so does exporting as standard html5 and testing on a local wamp webserver, so I'm not really sure what's going on.
