Most of what I've seen on dribbble are only iphone/ipad related work. Most of the designers there seem to know only about Apple software. Icons, designs, themes, you name it, all for iOS.<p>You have two platforms of which one will become much more popular than Apple's (as it already is) with emerging countries starting to have access to great hardware at cheap prices (Moto G, some Lumias) all of which are non-Apple.<p>I think android/wp needs good designers and there is opportunity for well designed apps. Everything you need is there: lenient rules regarding publishing, cheap to start and a less saturated market.
