I don't know if this is the right place for this question but I'll shoot anyhow. 1. What is the best application available for MAC (preferably free) for burning ISO images? 2. Which USB port on the back of the new Imac has constant power if any for charging Iphone or Ipod? (I heard this somewhere can't remember where though) Thank you, And sorry for being a Mac noob just got my first mac on Sunday. 24"
