Here's my situation. I have a Windows PC at home with a 2nd drive for my iTunes library on it. I sync my iPod and AppleTV to it. I am about to buy a new MacBook or MacBookPro. I'd like to transplant my iTunes collection to the laptop. That way, all of my content would be available to me whether I'm at work, on a bus, hotel, etc... Also, I can download TV shows I have a season pass for while on the road. Sounds like a simple plan, but... Then when I get home, what about the AppleTV? If my content was less than 40GB, sure, I'd sync & then shut down the laptop. But do I really want to leave a laptop running all weekend to stream to my AppleTV? There must be others in this scenario. The only option I considered was using iTunes on my laptop for music only, and keeping my old PC up at home with iTunes for video only, demoting it to more or less just a streaming server for my AppleTV. But I have a ton of videos in iPod format I sync with, so what about that? Maybe there's a simple solution I am overlooking. Any ideas?
