I am planning to learn Sencha touch. I heard Sencha touch-2 is the latest version. So I started to looking on version 2. Still I have a confusion that, whether I should study Sencha touch 1 also?
Some of my friends said that, knowledge in version 1 will not much helpful for learning version 2 because architectures are different in both.
Could you please clarify my doubts? And as a beginner, I found it is very difficult to follow the official document? Is there any simple document to start Sencha 2..??

Any single help would be appreciated...

Thank you....
