I don't see the point of putting more components in a display other than what needs to be accessible on the fly. Optical is a dead format, so there is no need for that. The power supply for something attached to a display? Pointless. If we are using a display as a hub, then it should only be used for what is absolutely necessary: USB, ThunderBolt, SD Card...perhaps a standardized SSD compartment (but I really don't see that either).

The current mini already has an internal PSU. It's already small enough to pick up and take with you and it works with just about any modern display. Get rid of the optical drive and it will get smaller. Better yet, if you're always moving between your house, work or 'cottage,' then get a MacBook.
