This is not Construct 2 fault, sorry but i just buy C2 for what it's aimed for, HTML5 GAME MAKER.
this how C2 is good at, mobile is just need time, in fact I trust Ashley words, he is right, the HTML5 is improving day by day, just try to compare html5 from dec 2011 and after dec 2012 ? their a huge improvements and that took just one year, i remember how html5 was so buggy and i remembered how tigsource filled with users saying this worst option for web game, and flash shouldn't die etc..
for mobile games, i use gamemaker studio, i hate to be like advertising another tool, but i just want to say, C2 is best for html5 game making tool who is fast forward and with easy physics support & webgl shaders.
yes it would be cool to have native export, but you should all understand this just one man effort, and the only support from you to him is to buy and spread the words about C2, it's possible one day native export will happen, or in fact the html5 might do the trick someday but not yet, hopefully soon.
in fact i believe this blame should goes to browsers and mobile manufactures, the issue might be more political than to be technical i believe..
sorry for my bad english.
