ATMs are a pretty common device, and they've been around a long time.
I would have hoped we would have this optimized by now, but it seems
interfaces are still (a) wildly inconsistent and (b) inefficient.
Most ATMs appear to (still) be designed for the first-time user,
which is frustrating for most people.
Here are two good things I've noticed recently:
* PC Financial (Canada): when depositing checks, you are presented
with a small ledger, where you can enter check amounts one at a time,
and let the ATM do the adding.
