I'm not going to repeat all the pitfalls and bear traps that come with these types of statistics, I assume we are all well and true familiar with them by now. Still, if you look at the progression of the figures, you can isolate trends, which can be just as interesting as definitive figures.
We can see that Windows' share has slowly been dropping, while Mac OS X' share has slowly been rising. The iPod Touch and iPhone are also climbing - obviously - and Linux always kind of fell by the wayside. Sure, it made tiny improvements, but it never reached any true milestones.
Until yesterday, when it broke the 1% barrier. It's now on 1.02% market share, thanks to a drop in Windows and Mac OS X. Some good news for the weekend, right?
