Update February 20: Books are now in stock at Amazon.com and all existing orders should have been filled. If you have a copy, why not post a review?
Juliana Aldous at Microsoft Press has photographic proof. I haven’t got my copy yet, nor has Amazon.com, but they should be available any minute now.
(Are they there yet? No? How about now? Not yet? Dang!)
If you’ve preordered a copy from Amazon, your copy will go in the mail as soon as the shipment hits the warehouse.
