Whats the focus?

Lately I have been wondering where I need to focus my research efforts, Framework 1.1 or Framework 2.0. So many code samples, webcasts, and other tutorials are now focusing on 2.0 at an alarming rate. I currently work in 1.1 most of time. Hey, thats what I get paid to do.

The Ying:
The 1.1 framework will be around for a while because many companies won't adopt 2.0 for at least 2 years.

The Yang:
If you don't keep up with the new, the learning curve will be that much greater when you have to use it. How to find the time....

Do I wish to become specialized in a particular area or gain a great general knowledge. These are the questions that I am trying to figure out
