Imitation iPods. Are usually cheaper than actual iPods, but may have less of a life span (however, that's under debate considering the life of a regular iPod). Sometimes, imPods work just as well as iPods. However, Apple probably does not want you to buy imPods.
Person 1: I got this really cheap imPod yesterday!
Person 2: Does it work well?
Person 1: Almost as well as regular iPods. iPods might have a lot of features, but imPods are where it's at!
