Have not you got something better to do than to rant on about grammar?

OR

Haven't you anything better to do than to gripe about something so insignificant?

Same question, different ways of expressing it. English comes from a combination of Latin, Germanic and Greek languages. So, the grammar of English isn't as simple and one can express the same answer in many different ways and still be understood. Is not English Great?
P.S.
the professor is correct, it is 'between you and I' not 'between you and me'
