Latest Android Platform Version Distribution

The vast majority of 1.5 based phones in the US will be getting upgrades to 2.1 in the next couple months.

Only phones not getting updated to 2.1 will have paths to 1.6.

Google has declared its own apps will target 1.6 and 2.1 and vendors (at least in the US) have been working on getting their phones upgraded these past few months.

1.5 is a dead platform and I suspect at least from the US that graph will look very different by winter.

What i would really like to see is the geographical distribution of those users, just to see if there is some underestimated market that could be reached (e.g. what is the percentage of chinese/taiwanese/japanese users?).

Surprising to see 1.5 leading these numbers. It seems the complaints about fragmentation aren't unfounded.
