I love my iPod mini. It has gotten confused a few times and needed to be reset, but we've had no other trouble with it. The size, style, and features are excellent.
iPods are great to have along when walking the dog, and our dog now knows about it. If you pick up the iPod, he assumes he's going for a walk, so he starts his pre-walk happy dance as you disconnect the iPod from the iMac.
