If I understand the Apple Store correctly, the only difference between the two current models of the ATV is the hard disk size, correct? I am considering getting one, and want to be sure I'm not shooting myself in the foot by getting the one with the smaller drive. Right now I have an iMac that is always on and connected to my wireless G network. Therefore, I can either stream iTunes movies directly from the iMac, or worst case, synch the movies to the ATV temporarily. If I have a large amount of network storage capacity, is there any reason I should consider the ATV with the larger hard drive? AM I missing any obvious issues? Thanks in advance for all of your help!
