I have recently switched to a Mac and was wondering if Itunes music store is a better place to purchase audio books or another source? My whole life I have used alternate ways of purchasing my music, audio books, and other sources. It is really hard to change to a whole new way of doing things. What is the best way to switch to itunes, without losing my process of organization I already have? Macs are really amazing, but I am losing productivity since I switched from a PC, because of all the new hotkeys, mouses, and scrollbars that are all new to me. How long does it take to adjust?
