I am thinking about buying an Apple TV. I have several movies, lots of music and listen (or watch) several podcasts. However, my Macbook Pro only has about 20 GB of space left on it. That's not much room to build a media library around. I have a 500 GB USB hard drive but my iTunes library isn't on there. I guess what I am asking is there a way to add storage for Apple TV to use without a HD replacement in my MBP? Is there a good way to store my movies on an external drive for Apple TV? Or will it just wipe them out everytime it syncs? I think Apple needs to consider storage solutions for this media. I rarely buy movies from iTunes simply because I have no where to store them. I guess they want me to buy a shiny new iMac. LOL. Any suggestions or thoughts?
