Apple’s quest to bring iOS “back to the Mac” has now gone beyond the contents of the software in two key ways:
- Free upgrades.
- A steady, proven release cadence of one operating system per year, which increases the value proposition of a Mac purchase and helps get years out of one machine in an age where people will just toss PCs after a couple years.
In four years, my mid-2009 MacBook Pro — which shipped with Leopard — has gotten Snow Leopard, Lion, Mountain Lion, and now Mavericks. Contrast that with the computer I built in 2003 with Windows XP Professional: It was rendered mostly obsolete by Windows Vista (which arrived three years later), so I stuck with XP (with a Linux dual-boot as well).
