You raise the single greatest most valid point yet! It's not about those who download it and try it. It's about stickiness. Now, Angry Birds apparently has its fans (I'm not one just because I find the whole genre bland) but I know from experience that I'll down lite versions on my iPhone, often ad supported, try them out, and maybe purchase 5% of them as full, ad-free versions. The rest get dumped off the phone. Same goes with XBLA (Xbox) games. I've downed many trials but purchased only 1. It's all about live installs... not just downloads.
