LINQ is definitely worth the effort, and I am continuing with it now after couple weeks into it.
However, there are some gotchas, drawbacks, and bugs. Not all theoretical design recommendations for use of various controls and approaches are supported by working demos and examples.
So if you do not want to waste time running into gotchas and bugs, just make sure you follow the design patterns of published demos and examples already available on the web. Otherwise, feel free to experiment with new combinations of controls and approaches!
