So I finally ordered a 17" MBP to replace my faithful 17" Powerbook. It should be here next week. I'm just looking for some practical tips from you guys who have done this before. A couple areas stand out: 1. A year of Time Machine Backups - Are they basically no good and I'm going to have to start over again? 2. Is Migration Assistant the best way to transfer Mail settings, messages, etc... Calendar, Address Book? 3. I know PPC macs will boot only firewire drives, will Intel boot either Firewire or USB or USB only? I ask because I use SuperDuper to clone in addition to Time Machine backups. (I know they need to be GUID vs. Apple Partition Map.) Any other issues that stand out that will be helpful to know when this thing arrives?
