Used properly reference counted interfaces are very powerful and allow 
for some very elegant programming. Do you complain about AnsiStrings? 
They are reference counted. Would you really want to have to free every 
string explicitly? Dynamic arrays are similarly reference counted.

Reference counted interfaces allow you to create classes (and objects) 
that behave in the same way as AnsiStrings. IMHO, a lot of standard 
packages would be greatly improved if they used com interfaces.
