mperdue, you may have yours before my Migration from the old Mac Pro finishes up!
Right now it says 12 hours, but it started at 34 hours, so I think it has some wiggle room!
I don't have enough room on my desk for both Macs, so I have it set up in front of the bedroom TV stand where I could plug in to the gigabit switch behind the stand. The data should be transferring at 1Gb.
My iPhoto library is close to 150 GB, and my music collection is close to 200 GB. The Migration Utility closes all other applications while it's running, so keep that in mind.
Oh, and the label on mine says "Designed by Apple in California. Computer Assembled In China". I'm curious how close our serial numbers will be...
