I just received my new MBA today and I'm trying to decide how to use it best with photos and music. I have an iMac where I upload my pictures and manage my iTunes library. I don't need continuous updates to the library so I'm thinking my best bet is to periodically copy the iTunes and iPhoto library to an external hard drive (which I do anyway for backup purposes) and just have the MBA look at those libraries over my home network. The other method (which I don't know if it is possible) would be for the MBA to look at the libraries stored on the iMac. It is more important to me to not impact the performance on the iMac than having the most up-to-date music and photo library. I also would prefer to use a method which will make the MBA more responsive. Which of these two methods would be better assuming both are possible and is there a different method that would work well for my scenario? I don't have enough hard drive space to have local copies on the MBA and I don't want to use an external drive connected to the MBA. I definitely want to handle the libraries over the network. Thanks.
