Windows Phone Thoughts: Ownership of Windows Phones Holding Steady

WM Experts is reporting that, according to a Nielson survey, ownership of Windows Phone is holding steady. Blackberry is leading with 35% of the smartphone market, Apple is in second place at 28%, and Windows Phone ownership is at 19%. Android, the platform with all the thunder right now, only has 9% of the market - but I'd say it has about 60% of the mindshare. Given the number of Android devices shipping though, I expect that 9% to climb and climb over the rest of this year. The question is, who will bleed market share? I remember hearing a Microsoft person say that they expected market share numbers to get worse before they got better leading up to the Windows Phone 7 launch - I think he was prognosticating about this very scenario.
