Gizmodo readers are now confirming that the AppleStore is shipping their Mac OS X Leopard boxes. They sent them the notification, along with FedEx tracking number and estimated arrival time earlier this morning:
I just got a shipment confirmation from the Apple Store. They say I'll have my copy of Leopard by 10:30 a.m. tomorrow.
So there you go. The cat is officially out of the bag and into a FedEx box. [Thanks Kevin]
