Decided to learn Objective-C and iOS?

So you are learning Objective-C and all about the iOS framework to create iPhone apps. Keep in mind that you are investing in a closed platform and it might not be as valuable as today in 2-3 years time.

Investing in HTML5 and being able to create multi-device apps faster than writing ObjC, will be much more important in the future. 

In the end, everything is about user experience and about the ability to use APIs to reach private functions of the devices. 

Learn iOS and ObjC, but know that the moment HTML5 has the ability to provide the UX native apps have, it will be over.
