July was the month in which Apple released Mac OS X Lion through its Mac App Store. Later on this new OS was also released in USB flash drives which costs $69.99 whereas the downloading of OS X Lion from App Store costs you only $29.99. The USB stick loaded with OS X Lion is also sold with all new models of MacBook Air.
Since MacBook Air doesn’t contain the optical drive, so this USB stick is the only solution to restore to OS X Lion in case anything goes wrong with your machine and you couldn’t log into it.
