I'm kind of new to the Mac world and don't understand how everything works just yet. I love my Macs and have pretty much converted everything over to a Mac. Here's my question. I have a imac that is my main computer. This is the computer I use to sync my iphone now. When I got my MBP I plugged in my iphone to charge while I was on the road and that's when I learned that I could only sync to one computer for apps and stuff. So how am I going to get the apps, pics, videos and music on to my ipad? Isn't going to want to wipe out what I have now? I'm just not real clear on how this all works. Thanks for your help.
