That doesn't mean it won't prove to be useful in C#. People often underestimate how useful a feature will be when they haven't had it. Look up Blub's Paradox.
I don't think that apply very well. A rather big percentage of Java
programmers also program in C#.

In which case it would be interesting to see whether it becomes more requested in a few years' time, when those developers have been using C# 3 and become used to "var". It's too early to take results *now* and draw any conclusions.

True. It could change.

But I doubt it will happen. It is not exactly a new concept.

I don't even think C# would have gotten it if it had not been for LINQ.

No, you're missing the point - with var, you tend to concentrate on what you *do* with o rather than the exact type of o (which is part of the "how").
But what I do with o.m() actually depends on what o is !

But if it's obvious when *reading* the code what's going on, the details only matter when you're looking more deeply into the code.

I don't consider the type a detail in OOP.

When I'm working on a problem, I don't actually need to read most of the code closely - I'll skim a lot of it. Implicitly typed local variables help the skimming mode, and arguably slightly harm the detailed part.

I believe many people will want to know the type even for skimming.
