Linq, extension method etc - random thoughts

I find the c#3.0 center piece -- the LINQ feature -- a lot of fancy beautification features and syntactic sugar. I don't feel they
add any real capability that was completely "not doable" in C# 2.0.

However, Linq is indeed adopted in investment banks.

They certainly make c# source code more elegant, more natural, more like English, more "dense" but I feel in so doing they also add
additional layers of complexity. I don't know if this is the best direction for a language.

Linq requires extension methods. Compiler magically converts static methods into functions that appear to be instance methods of the
IEnumerable type.

Linq encourage lambda (in place of plain old delegates). Compiler converts each lambda expression into a delegate instance.

Linq encourages anonymous types. Compiler converts each such type to a real type whose generated name is known only to the compiler.

Q: What problems do you have with Linq?
A(from a veteran): slow for SQL
