Can the C# ‘var’ keyword be misused?

I think this is a nice future, for example look this code:

Dictionary< SomeClass, List < SomeOtherClass > > myDic = new Dictionary< SomeClass, List < SomeOtherClass > >();

We really need to tell the compiler in this expression what the type of myDic is? This is more concise and clear at least to me:

var myDic = new Dictionary< SomeClass, List < SomeOtherClass > >();

If you are developing an application, you should know the semantic of the method, then the code

 var productsTable = GetProducsDataTable();  

should not be a problem, if you are just reading the code, check this out.

List products = GetData();
foreach(var product in products)
// doSomethingWithProduct(product)

The no less readable code:

var products = GetData();
foreach(var product in products)
// doSomethingWithProduct(product)

I think this is dependant on the context. I'm completely sure that if you choose your methods and variables names well, the code written will be more readable.
