Android Fragmentation - A Useful Fragmentation Measuring Stick

I've been working on a pretty data-intensive model for looking at Android fragmentation severity over time. I wrote up a post about my findings here: Android Measuring Stick, and I think it's interesting for people to take a look if they have been hoping for a more rigorous approach to this issue.

Here are a few of the charts I use to illustrate my findings (full analysis and more charts follow the link):

Percent_20on_20most_20recent_20version_medium

Percent_20by_20version_20by_20weeks_20after_20launch_medium

Short story for those who don't want to click through: Honeycomb was the slowest version to enter the market, and ICS isn't taking off any faster: in fact, it's only adding about 200K devices every week, which is the same speed at which both Froyo and Eclair entered the market (when total Android weekly sales were much smaller), and is about 14 times less than the number of devices Honeycomb adds each week.

Let me know what you think!
