I always hated it too.  I find that merely picking good names for classes is 
usually sufficient if not superior.

However, in all fairness to Simonyi, he developed Hungarian notation 
literally decades ago, at a time when C compilers did not do any type 
checking and yet the types of variables mattered greatly.  It was easy to 
mistake ints and floats or much worse chars, char pointers and ints, with 
disastrous results.  In fact, I think he used it for assembly language 
programming before he used it for C.  In the absence of any substantial 
abstraction constructs and in the context of a very type unsafe environment, 
Hungarian wasn't such a crazy idea.  I personally STILL don't think it was 
worth the effort -- then or now -- but in the context of the time it wasn't 
so crazy as it may seem today.
