"The "marketshare" that is referenced by Kantar is new sales marketshare, not overall marketshare." The point is that the number of users of WP is increasing at a fairly decent pace. The most important thing is that people are using the phone. "All WP is currently doing is taking a small piece of the symbian/BB pie" That seems very difficult to prove and I don't believe there is anything out there that states this. I know several people who switched from Android to Nokia WP phones, and several more that are intending to make the change. This isn't proof necessarily but I could see it happening. Concerning #3: It's hard to say what the first version should have been. The iPhone didn't have many of the "standard" features either in version 1. The main question is whether the pre-mango version hurt or has helped Microsoft's cause. The fact that they've had the phone out there for a larger period of time I would think would be a positive thing, being that they've had so much more feedback as a result. "Overall, I believe WP will not go away, but will stabilize at around 5-6% overall marketshare. " That's reasonable, however I'm curious why you believe this? You don't believe many Android or iPhone users would be interested in switching?
