A very interesting graph. Shows Symbian has dipped significantly over the past couple of years while Blackberry (RIM) has stayed about the same.
Android has come from nothing to take pretty much all the share which used to belong to Microsoft with Apple taking most of the rest.
Symbian is, of course, still in the lead, although you wouldn't think it from most articles. The thing is that Symbian is on a lot of 'normal' phones that people don't buy because they are smartphones particularly.
