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.开发者_如何学编程..

Focus on flexibility. There is no "holy grail" language that is perfect for everything, so having the ability to adapt and learn as needed is important.

Perhaps you should look at MonoTouch/Mono For Android or Appcelerator Titanium if you want to write once and run on multiple mobile platforms.
