I have my iPod Touch sync'd with a specific pc, using it for loading all my music and media. I have another pc at the office, but on that office pc I just have a few bits of media I wish to add from the office pc to the iPod Touch now and again. How do I get the new media on to my iPod Touch without deleting all my Touch's media that was sync'd from my main pc? (assumes I have iTunes on the office pc) t.i.a. for help this is drivin me nuts.
