For interest, here are some new smartphone figures showing that Android has increased its smartphone market presence by another 7.4% since September. It has pushed Apple into third place and is right on Blackberry's heels now. Palm and MS continued to lose ground with MS dropping another 1.5% during the WP7 launch.

There's also data from canalys confirming that 32.9 million Android phones shipped in Q4 2010, exceeding Symbian that was the clear leader in Q1. This translates to >350,000 daily which seems to support the 200,000 daily Android activations that were reported earlier.

The important thing is that Android is booming, Apple is holding onto market share but all the others are going backwards. It's getting to the point where successful businesses won't bother to provide apps for the also-rans: e.g. check out Godaddy's Mobile App, http://www.godaddy.com/business/mobile-app.aspx ... a cross-platform development tool better than HTML may be MS's and Palm's only hope now.
