That was the original plan. But after the increased number of alien sightings when Emu farms started, they decided to go with something a little less noticable.
why upgrade when the current software provides everything you need
As technology develops, older systems become obsolete and non supported. For example my company uses a piece of equipment that was developed for Windows 2000. This company has since gone out of business. Now my company struggles with software that requires Windows 2000 and hardware that doesn't support Windows 2000. As time goes on we all are forced to upgrade, unless you buy plenty of spare parts. Sadly there is no places to stop in the computer world.
