I am getting an iMac soon and getting out of the Windows world, at least personally. I have a few questions related to this switch. 1. Is it simple to move my iTunes library from my Windows PC to the Mac, along with all the relevant information (playcounts, etc)? 2. My iPad and iPhone are all current associated with my Windows PC, do I have to have to reformat each and then plug them into the iMac or can they simply be plugged into the iMac and w/out having to reformat each device? 3. I have three older external hard drives that I use for backup on my Windows machine, can these simply be booked into the iMac or do they also have to be reformatted to work with the Mac OS? Thanks for any help you can provide. I'm looking forward to making the switch once and for all!
