I am looking for a way to synch my iTunes library on my macbook like an iPod. Basically, my main iTunes library on my mac mini is HUGE. Way bigger than will fit on the 250gb drive on my macbook. So I am looking for a way to sync my macbook in the same fashion as an iPod. I want to choose a few playlists to send over and keep synced. Maybe 50gb or so of data so that when I am away from my main computer I can have music with me. The reason I want to do this is my 30GB ipod recently dove off the deep end and I dont have the finances to get a new one yet. But I usually have my laptop with me most places and like to listen to music. I have found ways to keep 2 libraries synced but not be able to partially sync one. Anyone have any ideas on how or if this is even possible?
