Thanks for this analysis! But im still a AppMobi kinda guy <img src="smileys/smiley1.gif" border="0" align="middle" />. They have many great API's that Ashley is going to incorporate into C2, in app purchases and Ads ect. Overall AppMobi has more, But I do like the simplicity of Phonegap. But games simply cannot go without audio, no audio would make a good game bad unless the art is sooo amazing that having no audio could be part of the game maybe?
The only game I can think of that could get around not having audio would be Limbo <img src="smileys/smiley23.gif" border="0" align="middle" />, Simply because the game is amazing!
I think AppMobi's direct canvas will mean much better performance, but I do really like phonegap <img src="smileys/smiley1.gif" border="0" align="middle" />.
