It's been a couple of weeks, and that means it's time for an update as to who's running which version of Android. (See the previous breakdown here.) Fifty percent of Android devices are now running Android 2.1 (and if you count all of Eclair -- 2.0, 2.0.1 and 2.1 -- it's 50.4 percent. Android 1.6 is down to 25 percent even, and Android 1.5 is at 24.6 percent.
It would be interesting to see Android 2.2 numbers on that chart, however unofficial they may be. For what it's worth, our server logs for Monday showed 79 percent of our Android-OS visits coming from Android 2.1, and 7.35 percent coming from Android 2.2, with Android 1.5 coming in third at 4.59 percent.
