Harry appreciates Ron he just isn't very good at expressing it
Harry is a bit self-focussed i must say.He doesnt go out of his way to appreciate others,like Ron or Neville for instance. i think he didnt do justice at that occasion, even after Hermione described the situation to him quite clearly.
Also, till now everything has been portrayed with respect to harry, not much focus has been given to what Harry thinks or does to others. i think the above statement is not clear. like for instance, whatever harry gets for christmas and birthdays is told but never is it told what he buys Ron or Hermione, so i think Rowling should make Harry appreciate others a little more in the later books
