So until now I've had a 27" imac with a Drobo attached running everything. This has been the 'brain' center to serve up 3 appletv's, 2 iphones and 1 ipad. It's also where I store all my photos for iphoto, etc. Wanna purchase a mac mini to run headless as a media center for the appletv's. My questions come into play when it comes to itunes itself. So if have all the 3 appletv's (gen 1's) point to the mac mini...that means it needs to run itunes itself and have a library pointing to all the media. For the 27"...i'm going to need itunes pointing everything back to the mac mini right? So anytime i add music i'm gonna have to update both library's? So far all the iOS devices are synced up with the 27" imac...so I just maintain course with that? Was hoping the mac mini would simplify life but all of a sudden I'm thinking it slightly more.
