mahdi, please don't feel offended, but how come you're not even considering developing for the iPad? Forget the iPhone, or any other phone for that matter, they're too freakin' small! I really don't know anyone with a Windows tablet. I do know people with Android tablets (obviously) but most of them would never ever spend a single $/Euro on software. I can't see the downside of developing for the iOs. Hardware and resolution are fixed, the user base, and I mean those who actually pay for the software, is gigantic. All you need is a Mac (or a Hackintosh, for that matter) an iPad 2 and the annual $99 developer fee. I think 0ad would top the sales of the AppStore in record time. So, what are the downsides, please? Regards,
