My son is only a freshman so doesn't need many of the capabilities of this calculator yet.  But it does everything he needs and I have no doubt it will continue to serve its purpose in the years to come.  I was shocked that the school required such an expensive calculator, but at least it's one that won't become obsolete any time soon.  A good device like this will continue to be needed as long as classes ban phones in the room for fear of cheating.
