My dad's old pc is failing frequently and it is time for a new computer. I have a MBP and he's seen the things Macs can do. He is considering an iMac but he does a lot of emails using an microsoft outlook email address. How does that work with Macs? I have heard of entourage or mac mail, what is the best method of syncing his existing email address with his new Mac? Will it work 100%?
