Most people switching to the Lumia 900 or HTC Titan II Windows Phone handsets are moving from the iPhone and Android, at least according to a poll by WPCentral.
BlackBerry accounted for 10 percent, Nokia's Symbian almost 12 percent, and HP's WebOS a little more than 6 percent. That left almost 15 percent of Lumia 900 and Titan II adopters upgrading from feature phones.
The results aren't fully comprehensive since WPCentral didn't include Windows Mobile users or previous Windows Phone users in the mix. The site explained that it wanted to gauge the rate of people who switched from rival platforms to Windows Phone specifically because of the Lumia 900 or Titan II.
The results, though small and unofficial, seem to hold out some hope for Microsoft and Nokia.
As WPCentral points out, Nokia has been able to focus all its promotional efforts as of late on Windows Phone. That's a much-needed change from the efforts of Samsung and HTC, which have divided their attention between Android and Windows Phone.
