There were rumors of an iPod dock on a different version of the Mac Mini.
Anyone think there's a chance of a future Mac Mini w/ no hard drive for like $399? BYOMHdKM. You just hook up your iPod sync(say an 80GB hdd in a few years) and it has everything you need. Unplug it and take it to work or school and you have your entire desktop, files, OS, and all the apps you might need.
Why carry an entire computer around when everything you might possibly need fits in your pocket?
