Last year, it took 30 days of iOS 6 to reach a record 61% penetration.
By contrast, Windows 7 is still at less than 50% four years after Microsoft (MSFT) shipped it, according to NetApplications. That's because Windows 7 is still competing with Windows XP, a 12-year-old operating system that runs more that 30% of the world's PCs.
Apple hasn't said how many of the 700 million iOS devices it has sold since 2007 are still in operation, but Mixpanel's chart suggests that on Sept. 23, when Tim Cook announced that iOS 7 downloads had passed 200 million, the number of active iOS devices was roughly 350 million.
That means that as of Monday, 250 million were running iOS 7.
And in the Apple market, Lion is still trailing two-year-old Snow Leopard
In its final monthly report for 2011, NetApplications offers a window on the shifting fates of the various flavors of Microsoft (MSFT) Windows and Mac OS X that show up at its 40,000 clients' websites.
As a rule, creaky old legacy systems dominate.
Windows XP, which Microsoft introduced in August 2001, is still the single most-present PC operating system, with a MOREPhilip Elmer-DeWitt - Jan 1, 2012 10:56 AM ET
Steve Jobs' master plan to draw a generation raised on stolen music into the iTunes store
Of the 5,364 items in my iTunes music library, 143 are songs I purchased on Apple's (AAPL) iTunes store. The vast majority were ripped from my old CD collection. A few were obtained by other means.
My children have even larger digital music collections that they store on iTunes and play on their Apple devices. I MOREPhilip Elmer-DeWitt - Jun 7, 2011 7:16 AM ET
Could a friendly fungus eventually eliminate styrofoam packaging? Don't laugh, it just might.
FORTUNE -- If your job was to ship 250 pounds and $25,000 dollars worth of computer servers, you'd no doubt pack them in a box using only the safest materials. And yet when Dell (DELL) ships four of its PowerEdge R710 servers it will soon offer a new packaging made of...mushrooms.
The idea seems off-the-wall, but it also seems MOREScott Woolley - Apr 5, 2011 3:21 PM ET
Why would Symantec's CEO suggest that Macs are just as vulnerable as Windows PCs?
Maybe to sell more anti-viral software.
That's the only explanation I can give for Enrique Salem's performance in a video posted on CNNMoney Thursday entitled "Macs are no safer than PCs." (Video below the fold.)
Fortune's Adam Lashinsky asked Symantec's (SYMC) CEO several different ways whether a Mac was as likely to get attacked by malware as a MOREPhilip Elmer-DeWitt - Feb 17, 2011 2:40 PM ET
Generic PC users are happier than they were, but still not as happy as Apple's customers
The chart above, posted by my colleague David Goldman at CNNMoney early Tuesday, says it all.
The release of Microsoft (MSFT) Windows 7 helped undo some of the damage done by Vista, as measured by the American Customer Satisfaction Index's 16th annual survey of computer users. But Apple (AAPL) remains in the lead for the MOREPhilip Elmer-DeWitt - Sep 21, 2010 6:58 AM ET
There are at least 32 in the works. Technologizer has the definitive round-up.
Nothing breeds imitation in high tech like a runaway Apple (AAPL) success. Even before the iPad was unveiled, Cupertino's competitors were scrambling to catch up. Now that Steve Jobs' latest invention is clearly a hit, the rush is on.
How many iPad wannabees are out there or in the works? Technologizer's Harry McCracken stopped counting at 32, but he MOREPhilip Elmer-DeWitt - Aug 15, 2010 5:51 AM ET
Microsoft's latest pitch on the Web for Windows 7 is a six-point Apple attack ad
Where are John Hodgman and Justin Long when we need them?
It's been more than nine months since Apple (AAPL) issued its last three "Get a Mac" ads -- aired, not coincidentally, the day Windows 7 launched -- but the sting still lingers in Redmond, Wash.
On Monday, Microsoft (MSFT) took another crack at countering Apple's three-year television MOREPhilip Elmer-DeWitt - Aug 10, 2010 6:48 AM ET
Analyst sees Apple taking 35% to 40% of the tablet and e-reader market in 2010
In a note to clients issued Thursday, BMO Capital's Keith Bachman offers several reasons for raising his price target on Apple (AAPL) to $265 a share from $250, including a 17% increase in Mac sales and the likelihood that the company will release a new iPhone in June.
But the biggest change in his model -- and MOREPhilip Elmer-DeWitt - Mar 25, 2010 12:00 PM ET
Don't look now, but the year's most buzz-worthy tech company might be Microsoft.
Microsoft went around with a big, fat target on its forehead for a couple of decades. It was the tech giant we loved to hate. The company deserved the scorn; in the 1990s it crushed pipsqueaks Apple (AAPL), Netscape and Palm (PALM), and still found time to push around a few hapless PC makers who seemed to barely MOREJon Fortt - Feb 26, 2010 9:39 AM ET
