This line really had me salivating over thoughts of a PC-based platform that would natively run all current iOS/Android/WP7 apps without needing to buy those respecting phones. There are some really great iOS-only apps out there I'd love to try but can't justify getting an iphone just for that. It'd be awesome if someone made a universal platform that would allow you to buy apps from all the different phone app stores (you'd still be buying apps direct from Apple so they would still get their cut) and play them right on PC.
It could turn out to be a good opportunity for some android developers as only developers from only few countries(25 something) are only allowed to publish paid apps on google play, the largest, biggest, most-known android market. There are other non-android market's too, but they are less popular and less beneficial for developers, because of less traffic. But facebook, everyone knows about facebook, so its a great platform. I hope they do give support for all countries though.
