They are also in the majority of tablet owners.
Which is not mutually exclusive from either of my two observations. However, you're making a gross assumption. Just because the majority of tablet users may have an iPad does not mean that's the OS they prefer. It simply means that at the time of their purchase, that device was the one that met enough of their wants/needs that it was the overall preferred device. It's very possible, perhaps even probable, that some very much prefer Windows, Linux, or even MacOS, but in the tablet space the iPad simply has the applications they need most. I know many gamers that prefer Linux, but still have a Windows box or dual-boot because gaming is just so much more accessible on that OS.
And none of that in anyway disproves what I said before.
