Answer: WINDOWS. The number of home and small business Linux users is a tiny fraction of that of Windows. And that's why Windows gets attacked and hacked with far more success than Linux: there's far more of them and the majority of home and small business users have no idea how to secure their systems.

Sorry, but this old canard was disproven years ago when someone designed and exploited a router vulnerability with the "Witty Worm", that had an estimated global target of 10-20k devices.

Also, with the prevalence of Android devices, which are essentially special-purpose Linux devices, I think you might find that these days there are actually more Linux devices in use than you might think. I've seen estimates that there are more of those extant these days than MS-windows systems, but I'm not confident in the sources.

In the interest of objectivity a quick Google search turned up the following: Android is the predominant OS beating Windows

Not that I trust Wikipedia for much of anything, this at least seemed to be somewhat unbiased.

So I think this proves your point that Windows isn't the predominant OS. :-)

The exact google search phrase I used was "number of linux vs windows devices worldwide" which turned up a plethora of links saying Android was #1.

I'm happy to be objectively corrected.
