Question: what should one focus on when there is a strong need to develop Apps for multiple platforms? I spend all this time focusing on Obj-C, but that get's me no where with Android, Windows 7 or Blackberry.
At it stands, Objective-C isn't even the language that the iPhone ends up using. Obj-C is compiled for the iPhone. So there must be a way to write the Apps in a more global language and then have it compiled for the iPhone, Android and Blackberry...
Recommendations?
