Android is still growing at a fast rate. Nielsen Research has released the latest numbers and in the past 15 months devices sold with the Android OS has risen to 43%.
Apple has held fairly steady at 26% and BlackBerry has taken a bad hit down to 20%. This is not very shocking. It seems new Android based devices are being released daily and are very affordable. If Android growth continues at its current rate Android could easily surpass 50% by mid 2011.
