I'm not sure if this gives me the information I wanted though. For
instance (I may be wrong) there seems to be no way to distinguish
between visitors to the desktop and the mobile site on certain
browsers.

As a real example I'd like to know how many people are using Internet
Explorer < 9 to access the mobile site m.wikipedia.org.

Countries would also be useful - are there any plans to explore this?

I happen to have done some research on the mobile site more or less by accident recently. Of the non-bot access to the mobile site, 2.8% came from non-mobile browsers - although the actual number may well be even lower, because a significant part of that is shown as NetFront, which is mostly used in mobile browsers.
