There is much speculation that the HDD is there for reasons other than caching iTunes files. Who knows? I'm happy with my current DVR which is provided by Comcast. I just needed a device to hook up to the media on my computer. And HD is certainly a big plus. I have a Mac mini on my desk at home. I suppose I could have used it instead but I want to keep it in my office because it's mine! My own! My precious!
