Well...
1) My language preference should be on my card. Meaning, when I insert my card it should know whether I want English or Spanish based upon my card preference. I hate those questions.
2) As the previous poster said, arrows rarely line up.
3) Some ATM's offer Stamps, Tickets, and other things. This might be handy but I only did it once for the novelity, not sure how much use these really are. The stamps might be, I don't know.
4) This falls under #1, but I think you should be able to have some type of "Remember Me" preferences. Like for example, I also take out $40 from an ATM or whatever. It should be able to insert my card and have it come up and say... want your usually $40? I hit yes and it gives it to me and closes out the transaction and gives my card back.
5) Eliminate stupid charges on other ATM machines not owned by the Bank.
