Stick a fork in the Mini, it's done.
The Nano is fantastic. People loved the Mini because it was smaller than an iPod, but really it wasn't THAT much smaller... whereas the Nano is.
borghe is right -- the Mini was successful because it hit an audience that either didn't have that many songs or didn't want to carry that many songs (something that Apple is trying to capitalise on further with the Shuffle), and the Nano will only take it further.
I know the old argument: For $50 more than a Mini/Nano, you get a full-sized iPod with five times the capacity. But with the Mini, people never saw it that way. They figured they didn't need the extra space, liked the smaller player, and they save $50.
The phone, however, is crap. It needed a distinctive, RAZR-esque look to stand out -- because it doesn't stand out at all. This is supposed to be some sort of signature, flagship phone, but it looks like a run-of-the-mill Motorola. Also, while it's nice that they're copying (most) of the iPod interface, the menu system alone isn't what made the iPod so easy to use. The wheel was really what made the iPod's UI so innovative, and that's missing from this phone (though to be honest, with a 100 song limit...).
