In addition to hard drives containing OS X Lion for installation on store computers, some of Apple's retail stores are also reportedly receiving new maxed-out Mac Pro machines, according to 9 to 5 Mac. The report speculates that the Mac Pro machines may be used for local caching of Lion for delivery to customers coming into the store to purchase the new operating system from the Mac App Store.
Furthermore we've heard rumblings that some stores will be receiving maxed out Mac Pro towers to be used as Lion distribution caching centers (speculation here). Some believe that these stations would allow customers to purchase Lion (3.5GB) from the Mac App store and download it directly from the store server in minutes rather than hours it takes over a normal broadband connection.The new hard drives containing Lion have also been said to contain three separate versions: Normal, Pro, and Joint Venture. The different versions would be installed on various machines throughout the stores based on their roles within the store layout. Basic machines would presumably receive the Normal version, while higher-end machines showing off more advanced apps would receive the Pro version. The Joint Venture install would presumably be reserved for those machines utilized by the program of the same name, which focuses on businesses.
