In July 2008 (when StatCounter started recording OS share) XP dominated the market with 75.07 percent. Today it sits on 15.84 percent — a drop of 59.23 percent. But while XP was tumbling, Windows 7 was rising at a meteoric rate. It’s a clear upgrading picture — one OS ceding to another, newer one. That picture is totally absent when you look at the impact that Windows 8.x has had.
From launch on October 26 2012, Windows 8.x took 18 months (with a little rounding up) to get to where it is now — 13.73 percent. 18 months after it launched on October 22 2009, Windows 7 was at 33.22 percent. At the rate it’s going (an average of 0.76 percent a month), Windows 8.x will take another two years to reach that mark, assuming users of other operating systems (Windows 7 and XP) decide they want to make the switch. Of course, the keyboard and mouse friendly improvements added in Windows 8.1 Update could see the tiled OS pack on market share at a faster rate, but it’s too early to know.
I think that’s been obvious long since. Windows 8 is the only version of Microsoft’s operating system to date whose release drove up its predecessor’s sales.
Windows operating systems still have 88% of the desktop market, the balance being OS X, Android, and Linux.
It might be claimed that market share of desktop operating systems is irrelevant because the PC is dead but that reflects a misunderstanding of the U. S. market. The U. S. computer market is completely mature; just about every prospective customer already has what they need. That’s not just true in the desktop sector and mainframe sectors but in the smartphone and tablet sectors as well. More new businesses could spur additional desktop sales or some “killer app” could boost tablet sales but barring those eventualities the market in just about every sector of the computer market from handheld to mainframe is mature.
Mature markets operate drastically differently than new ones do and American computers companies haven’t adjusted to that reality yet.
