Building and dismantling the Windows advantage
When the Macintosh was launched in 1984, computers running the MS-DOS operating system were nearing a dominant position in the market. Having launched in 1981 as the IBM PC, they were quickly cloned and four years later “PCs” were selling at the rate of 2 million/yr.
Context & Ripple Effects
Asymco's argument runs through the origin of the Windows advantage itself: IBM's 1981 PC ran MS-DOS, was cloned almost immediately, and by the time Apple launched the Macintosh in 1984 the compatible 'PC' category was already selling at roughly 2 million units a year. Cloning made the platform ubiquitous; ubiquity, not interface superiority, is what entrenched it.
The data point reigniting this history is the PC-to-Mac sales ratio, which per the syndicated pickups at Business Insider, The Verge, and the Telegraph has fallen back to levels not seen since the 1990s. That reframes two earlier debates in the corpus: whether 2011 really isn't 1995 for Apple, and Bruce Tognazzini's claim that the iPad repeats the Mac's history — this time with Apple holding the integrated position rather than fighting the clone army.
First-order effects
- Apple's Mac business is closing the unit gap against the entire cloned-PC ecosystem, turning a metric Microsoft and OEMs long ignored into a headline across Business Insider, The Verge, and the Telegraph.
- Microsoft's licensing model — collecting per-copy fees from many hardware makers — now faces a rival whose integrated hardware-software model grows share without needing clone volume.
Second-order effects
- PC OEMs whose margins depend on Windows volume face a competitor that competes on the whole system rather than the OS license, pressuring them to differentiate on hardware design instead of price alone.
- The ratio's fall hands Apple a marketing asset: 'levels not seen since the 1990s' inverts the old narrative that the Mac lost the platform war.
Third-order effects
- If the pattern holds, platform advantage shifts from installed-base lock-in via cloning to control of the integrated stack — the same system-level logic the corpus tracks under fashionized computing, where desirability rather than compatibility drives purchases.
- Historical framing itself becomes strategic: both sides will keep relitigating 1984–1995 to argue whether the PC era's economics or the Mac's were the anomaly.
The trend: Personal computing is rotating from clone-driven, licensed-OS volume economics toward integrated hardware-software systems competition, with the PC-to-Mac ratio as its running scoreboard.
