True, but there are plenty of people yet to get an Android phone. These people will probably end up with a newer model that has all of these bells and whistles. I'm not really sure that Android has reached a 'critical mass' yet. Sure it's starting to out-pace the iPhone, but it still has huge potential for growth in the market. That these improvements are coming now, means that it will only help Android to grow (as the new handsets will come with v2.2 and all of the improvements).
That said, it would be nice if the carrier-branded Android handsets bothered to update more regularly...
