I'm curious what that tells you? Or at least what information you looking to derive. If I was a carrier, I may care how which handset is more profitable to sell, which once is in more demand, etc, based on what my network and my competitors sell. As an application developer you may care about how well the various Android market systems perform compare to the iPhone market place. Additionally as a developer you may care about the install base, or target demographics of that install base. I don't understand what factoring the number of sales channels (?) compared to sale volumes will give you statistically. (I'm always willing to be enlightened, I'm a developer by trade, so stats/biz dev is not my primary focus) [edit:] Additional thought, the rate of introduction of new smartphones on the Android vs rate of new iPhone releases. Conversely the iPhone introduced June 24th, will primarily show up on the Q3 sales figures (in the US).
