If there was ever a major, quantifiable difference between Google's Android operating system and Apple's iOS, it's that Apple users upgrade their Apple devices to the latest version of iOS much more quickly -- and in droves.

The latest iOS 9 adoption numbers for November 2015 were released by Apple this week, and the sheer percentage of Apple users who are now using iOS 9, and the speed at which they've decided to download the update since it was released in early fall, is breaking records yet again.

According to Apple's figures, as measured by its iTunes App Store on Nov. 30, 2015, a full 70 percent of Apple's mobile devices are now running some version of iOS 9 (including subsequent patches and updates through iOS 9.1). The share of Apple mobile devices running iOS 8 has now dropped to 22 percent, while iOS 7 or earlier were lumped together at a mere 8 percent.

Reaching 70 percent by late November represents a record adoption rate over recent years, even with the various problems reported over the past few months by frustrated iPhone users.

According to TechCrunch, Apple's iOS 8 last year was only up to 60 percent by the end of November. And the big aesthetic changes iOS 7 brought to Apple land two years ago still only managed to attract 74 percent adoption by the first weeks of early December of 2013.

Of course, iOS 8 came with a big storage footprint, which caused many iPhone users with the minimum 16GB of storage to either delay the update download, or forgo it entirely and upgrade their devices. And the year pervious, iOS 7 adoption -- the standing record that iOS 9 appears to be on track to beating this year -- benefited from all the hype surrounding Jony Ive's complete redesign of the system.

By comparison, the rate of Android 6.0 Marshmallow adoption is pitiful, as is Android 5.0 Lollipop adoption.

As of early November (Google hasn't updated its Developer Dashboard with December's figures yet), the Android 6.0 Marshmallow operating system, which was released weeks after iOS 9, has only hit 0.3 percent of Android's kingdom.

PhoneArena sarcastically noted that two months after Android M's release, Google's latest upgrade has finally surpassed Android 2.2 Froyo, which was released in 2010 and represents "the most ancient operating system version that's still supported in the Google Play store app." And Android M only managed to beat out the five-year-old Android operating system by 0.1 percent.

Even Android 5.0 Lollipop, now a year old, is only running on a little over 25 percent of Android devices, which puts the two-year-old Android 4.4 KitKat as the most popular version of Google's OS running on devices, at nearly 38 percent.

This comparison between Apple iOS adoption and Google Android fragmentation is always unfair to Google, though. Apple has the distinct advantage of designing and controlling both hardware and software.

And Apple's customer base is much smaller, less diverse, more affluent, and much more likely to upgrade hardware every year or two than the millions across the globe running some version of Android, manufactured by one of hundreds of companies.

As evidenced by its 2015 "Be Together, Not the Same" ad campaign, Google might have actually started to take its inevitable, incurable operating system fragmentation as a point of pride.
