Ok, I did a search on here and didn't come up with the answer to this one, so here goes and my apologies if it has previously been answered. I am PC desktop based now, with iTunes installed. I have an iPod shuffle which I love. My new company that I am consulting for works with Apples, so I will be purchasing a new MacBook very shortly here along with an iPod that will hold all my songs

. (I want to get the U2 Edition one!)
My question is, when I get my new Apple and iPod, of course I will sync the iPod to load it with my iTunes on my PC. When I plug it into my MacBook, will it sync all of the songs on it to there as well? I would love for it to be able to do that, as I will then load new CD's into iTunes on my MacBook.
Hope this makes sense and I look forward to the answer.
Thanks,

P.S. I have very limited expereince with Macs, so am excited about my MacBook when I get it!
