As expected, Apple has released OS X Lion on a USB thumb drive via their online store. The $69 thumb drive ships in 1-3 business days and requires 7GB of available storage space. One caveat for users that install OS X Lion via this thumb drive, rather than for $29.99 from the Mac App Store, is that re-installs will need to be conducted via the thumb drive; the internet-based Lion recovery system will not function.

The USB thumb drive is currently available on Apple’s online store across the globe and will shortly make its way to physical stores as well. OS X Lion brings over 250 new features to the Mac including system-wide multi-touch gestures, Launchpad, Mission Control, and iPad-like mail client, native full-screen application views, an improved Safari web browser with Reading List, automatic file saving, and AirDrop file transfers.
