This is active users in the US only.
iPhone now tops WinMo and is second only to RIM. The only line that is going down is the dumbphone category which lost 10 million users.
Those users were mostly switched to RIM and Apple. RIM gained about 4.3 million users and Apple gained about 3.5 million.
Android user base still lowest of all platforms and increased by about 0.6 million. They are likely to beat Palm however next few quarters. At this rate however it’s very hard to see an installed base that is going to challenge Apple for a long time.
Palm gained 0.44 million. Symbian gained 0.41 million. WinMo gained 0.3 million.
With a 1.4 multiplier for iPod Touch, the platform would have 12.5 million users, pretty near RIM’s base. We might see that tipping over next quarter.
