Bringing up my old "We need an app store" thread...
If you have a number of $5 (max $30) apps/games easily available people will spend their money, generously. We just don't want to spend $80 on the classic disc based game or $130+ on some productivity software that may end up sucking.
I hope there is a lot development for AROS because I will happily jumped over to that, but only if it has some promising developers for it. If there is nothing, but complain that "there is no money", "it's not worth it, I could develop on system x", I will be hesitant.
