Query: professional?

I kinda feel like a nerd using this one in class because everyone else has the "unprofessional" one. Who do I think I am? It works just like the cheaper version, just looks a little different. So if you are one of those elitist bastards who enjoys the attention when you whip out your iphone in a room full of razr phones then this is the calculator for you. Otherwise, just get the plain ol' BA II plus. The professional won't do your homework for you or anything like that.
