When I got my touch in the mail, I was at work, where I (sadly) have a PC. Not wanting to wait to play with it, I plugged it into my PC and did the initial setup, but didn't sync anything to it. When I got home, I plugged it into my iMac and synced everything to it. So my question is, did hooking it up to a PC initially do anything different to it than hooking it up to a Mac would have (like using more/less memory)? If so, is there any way to undo it? I'm not having any problems, I'm just curious. Thanks.
