The Register published the following news on their website a few days ago:
A new study conducted by IDC and mobile-developer platform and services company Appcelerator has determined that as Google’s open source Android operating system becomes more and more fragmented, fewer and fewer developers are putting it on their “must-code-for” list.
When this subject comes up, I always point to these statistics, published by Tweetdeck in October 2010:
If the Android ecosystem was that fragmented already 18 months ago, consider how fragmented it is nowadays now that we have Android 3.0 (Honeycomb) and 4.0 (Ice Cream Sandwich) added to the equation.
Oh, and don’t forget about tablet support that was added to Android 3.0, which makes the number of screen sizes and types of hardware even more diverse than it was 18 months ago.
