jn2002dk it was not a accusation, i just think HTML5 perfs on PS VITA will stay poor as you say before. As for iOS/Android the answer to this problem "can" come from specific product such as cocoonjs but if sony want to give a future to html5 on PS VITA they have to work better too.
So just to say that i think scirra team will never put time in specific PS VITA export features and i really don't wait for them to do so !
