Mac users four times more likely to run latest OS than Windows users
Some sums done by ComputerWorld show that Mac users are four times more likely to upgrade to the latest available version of the operating system than Windows users.
Microsoft has convinced just 11.6 percent of Windows users who acquired their system since 2001 and still actively use it to go online to migrate to the current edition of its operating system […]
Apple’s convinced 41.6 percent of Mac users who acquired their system since 2001 and still actively use them online to adopt the current edition of the OS.
A large part of it is cost, of course: Mavericks was a free upgrade, and previous upgrades have been priced far more competitively than Windows.
But Apple has also offered a simpler upgrade path, adding features rather than making major changes to the core user-interface. OS X also operates more efficiently, allowing Mavericks to run well on far older hardware than is the case for Windows 8.
