I wonder if the slowdown is related to the slow progress of getting ICS updates out. Just about every review of gingerbread phones I read lately includes a browbeating about lack of ICS and skepticism/uncertainty about manufacturer claims about future updates. Hopefully people have taken Motorola's advice to heart: don't buy any phone unless you're happy with it out of the box. ICS phones started showing up in stores in earnest recently so it will be interesting to see if the trend continues.
Does anyone else think that Android activations in the US will strongly rebound with the release of the Samsung Galaxy III?
Interestingly, Windows has gained US mobile share in the last two quarters. Will that trend continue?
