Horace Dediu: A fuzzy snapshot of the mobile phone market

FORTUNE — “Tracking the mobile phone market hasn’t been getting any easier,” writes Asmyco‘s Horace Dediu, who does it as well as anyone. “The lack of published data from many incumbents (including the largest) is compounded by the lack of visibility into entrants.”

Nonetheless Dediu managed Tuesday to publish what he calls a “fuzzy picture” of the market as measured by unit sales.

If he were graphing share of mobile phone profits, the picture would look very different. It would be dominated by Apple (AAPL) green (53%, according to Canaccord Genuity) and Samsung tan (50%).

That adds up to more than 100% because so many mobile phone vendors are losing money.
