The Android Market, which host Android apps has a lot of catching up to compare to iPhone, but it is surely picking up pace. In March, over 9,000 were added, and based on the graph, it looks exponential!
As more Android phones are introduce, the apps market will sure pick up. But with so may different platform in terms of screen size, processor, OS version.. etc, I truely hope Android will not fall into the Window’s Mobile trap of too many phone specific apps. Which is why I think iPhone is this successful so far, sometimes control freaks are good. That’s my take.
