FWIW I haven't received mine yet either, but that's not unusual. It usually shows up here in the middle of the issue's date, so that will be the end of March. I figure someone walks it from Boulder to SF, then someone paddles it in their canoe to Honolulu, where it is mailed and flown to my PO box in Hilo. Should be arriving any week now.
But hey, sounds like with all these fancy-schmancy authors writing in this issue, it will be worth the wait!
