You're linking to a chart that only talks about handsets when it comes to iOS, and ignores the iPod touch and the iPad. It was written in January and a good chunk of the iOS devices sold have been sold since.
According to Apple, at the time of WWDC, iOS was the largest mobile operating system, across all devices (using that standard since you said "all iOS devices") with approximately %44 market share to androids %35 market share.
Of course it is difficult to know for sure, because so many sources of stats only count phones (ignoring the iPad and iPod touch) and the stats for android are not very clear either with many manufacturers shipping large quantities of android tablets that have not, apparently, been selling thru to customers.
My guess is that even if 44% is 'all iOS' and android matches only to 35% of that, the remaining '9%' of iOS devices plus all OSX installs are dwarfed by the remainder of all (non-android) linux installs, which I think was the original point.
Out of curiosity, I wonder what OS Apple's embedded devices use, such as the wifi access points?
