I'm wondering now whether this is a fair comparison, Linux vs Windows that is, especially comparing the entire Linux family to just Windows 7 and it's various flavours. A better comparison would probably be to compare all Windows distributions with all Linux distributions and I think we can all agree that even in that situation there are more Linux distributions and flavours than Windows by quite a margin.
What I do think we also need to take into account is that Windows is proprietary and Linux is free and OSS, which is probably the reason for Linux having so many distributions out there. The problem now lies in the fact that Linux distributions are made by different people all over the place, so again I think that comparing Linux to Windows is unfair.
You need to consider one company that makes (an) operating system(s) and compare what they have vs what Microsoft has. So for this article, I think the writer was getting at Google, with Chrome and Android, vs Microsoft, with Windows desktop and mobile and which one is more "fragmented". (at least that's what I get from his last few sentences...)
Google has Android for cellphones and soon will have ChromeOS for desktops. Android by itself has versions 1.0 to 2.2 but the recent
pie chart suggests that Android users are now using:
- 1.1
- 1.5
- 1.6
- 2.0/2.0.1
- 2.1
So 5 versions in total, not counting the imminent release of 2.2.
ChromeOS is yet to be released, so we are left to speculate. I don't see this having Home, Professional, Ultimate etc. type versions for it. Lets say it gets on to tablets, then it
might have two slightly different versions.
This means that between mobile and desktop Google will have something in the line of 7 versions total whereas Microsoft has quite a few more. Is this a fair comparison? I don't know anymore. What I do see here is that everyone is fragmented to some degree and people are trying to point out that others are worse than them (w.r.t. fragmentation) on some or other level, so therefore they aren't fragmented. So I'll agree with the authors last point:
