Nielsen released data on smartphone market share as of Nov 2010 to Jan 2011. From an OS perspective, definitely it shows the Android juggernaut’s seemingly unstoppable rise to the top. From a hardware perspective, it’s interesting to note how Apple and Blackberry(!) still hold a huge chunk of the market. But HTC is waiting on the wings.
It seems that at this point, focusing on iOS development is still a good strategy. Noting, of course that the other iOS devices, iPad and iPad 2, are the leaders in the tablet space. But investing in Android development should already be in the pipeline.
