Is Nokia going to confuse consumers?

I saw the leaked 720 and 520 images and instantly thought "Wow, those look familiar."

Sure to us, we can judge on the specs and options, but if someone like my mother or a less technologically informed person goes into a store, how will they differentiate between all of Nokia's options?

Don't get me wrong, I like the idea of "tiered" devices, ie low, mid and high, but there needs to be some way people can tell the difference easily I think. Or am I just totally off base here?
