We like to poll our readers every few months to understand the breakdown of operating system usage so that we can appropriately cater our content. So please tell us: are you keeping it old school with Windows Mobile, rocking the shiny new Windows Phone 7, keeping it simple with iOS, staying professional with BlackBerry, flipping through cards with WebOS, or perhaps you’re in the “other” category running on Symbian or, heck, even Garnet OS (Palm original)? Let us know!
