Apple's Mac OS 10.7 has gone physical today with the introduction of a $69 USB thumb drive. The flash storage stick provides you with a full copy of Lion OS X, but does so at quite a premium relative to the $29.99 price of its Mac App Store alternative. Somewhat ironically, the newly corporeal Lion is only available for purchase through the online Apple Store for now -- delivery time is listed as between one and three working days -- though brick-and-mortar Apple outlets will presumably have it in stock very soon as well. One note of caution is provided: installing Lion from the USB drive means you won't be able to use the online Lion Recovery tool should you wish to restore your OS. Subsequent reinstalls will have to be handled from the flash drive.
