Mine arrived yesterday too, a day early. (Ordered 1.3/512/SG on April 15; delivered May 20.) Picked it up after work but didn't have time to set it up last evening, only enough time to spend a few minutes caressing it. On the road now for the rest of the holiday weekend.
Hope you're enjoying yours!
I bet our serial numbers are right after each other.
I do love my new rMB. It is prestine.
