Is anyone able to advise me on this... I know you can't sync an iPod to any more than one iTunes library at a time (well, without various hacks etc.) However, what I'm planning to do is take a laptop on holiday with me (with all of my songs/videos and an iTunes library on it - possibly a Macbook, but maybe a Windows laptop), purchase my iPod Touch, and sync with it, so that I can use the iPod during my vacation. However, when I get back home, I want to be syncing the iPod Touch *only* with my main Windows PC - not the laptop. The PC will also have all of my music and videos etc. So, first question: if I sync to the laptop first, am I able to come back home and sync only to the PC without too many issues? I'm mainly thinking of things like the 2.0 software update. For example, say I get a Touch just shortly after 11 July, and the 2.0 update is not on the device, but Apple give me a voucher for the purchase the update via iTMS. Will moving the Touch from the laptop to the PC scrub the 2.0 update, giving me hassles in trying to get it re-installed, or will a new sync setup simply wipe my tunes/videos and let me set up a new library?
