Mike, further to previous discussions, I thought you might be interested in latest mobile OS predictions from Gartner:

Internationally Symbian is predicted to maintain a 40.1% OS market share at the end of 2010 followed by Android with 17.7%, BlackBerry with 17.5%, Apple iOS with 15.4% and Windows Mobile 4.7%.

Bearing in mind that Symbian figures include Nokia's huge mass-market segment that's not really comparable, it still means that three OS dominate the data phone market with Gartner picking Android as the main contender in the US by the end of this year.

By 2014, internationally Symbian is predicted at 30.2%, Android at 29.6%, Apple at 14.9%, Blackberry 11.7% and Windows 3.9%.

The horse to back seems obvious enough, especially if you look at the 2009 figures: Symbian 46.9%, Blackberry 19.9%, Apple 14.4%, Windows 8.7%, Android 3.9%.

When you consider that VFP's pseudo-support is still live until 2015, the rapid progress in mobile devices is astonishing and clearly the place to be for people who want to ride the technology rollercoaster again.
