Well, what have you actually expected? With thousands of new application each month, with lots of new smartphones hitting the phone carriers week by week and with enough quality delivered, why shouldn't Android grow in charts? I think everybody expected Android to grow steadily, and they did it. There's a new report showing Android is at about 20 percent, while iOS is well in the fron, with 58.8%. Android shares increased since last October, up to 4.6% for the quarter and 12.2% for the year. 

The big difference between iOS and Android is not made by iPhone, which has just 10.7 million compared to Android's 8.7 million units. The big gap is made by iPad and iPod Touch and this makes the big picture more difficult to undersand. If one thing is for sure, then that's Android fast growth and if Froyo will be a hit on the market as Android 2.1 was, then it's more than sure there is going to be a clich between iOS and Android soon.
