What is the advantage of having a larger drive on the TV? DVR macmini substitute I dont see the advantages; it is a streaming hub correct? Anyone find the onboard storage useful for anything but trivial importance? Perhaps moving the device to a non networked environment, or on the off chance the network goes down Any valid reasons to opt for the larger drive or replace with larger/add external? Getting one for my mother possibly soon depending on the rumor mill and update information, specifically hoping for DVR capability update, though I dont know how this would fit into apples marketing strategies at all, but it sure would be nice for the consumer! Throw us a bone apple, please. Can the DVR functionality be accomplished by a macmini, keeping in mind it must be dead simple to moderately simple, for non tech savvy user, a lot to ask for but hopefully as simple as front row is to use, to simply push a button and have it record? In this case waiting for a wireless N spec macmini update would be the tactic, correct? Any info or thoughts? Thanks for the time and insight into the topic.
