"lambda expressions are just delegates (or type-safe "function pointers"). They only look as they are because some assumptions are taken (like a lambda expression are functions and therefore always returns a value) and the types can be automatically fetched by the compiler. The nice side effect is that lambda expressions save us a lot of typing and time."- http://msdn.microsoft.com/en-us/library/bb397687.aspx
I was compelled to learn Lambda expression, currently, I don't see lambda will save any typing time (viewpoint may change in future).
I kind like the lambad expression now.
