One of Windows Phones big knocks is that is doesn't have enough apps on it keep it's user satisfied and while it is missing some big name apps (I am looking at you Instagram and Jetpack Joyride) in general it has enough to satisfy it's owner. Microsoft is spending good money to make sure that apps keep rolling in for Windows Phone users and it is working. In fact according to Todd Brix (Senior Director of Windows Phone Apps Team).
Over the last year we've certified and published over 75,000 new apps and games (more than doubling the catalog size)
This means that there is around 150,000 apps in the Windows Phone portfolio.
It is also to be noted that you can now pay for your apps using your Pay Pal account along with credit cards, and carrier billing. So what is your magic app number where Windows Phone has respectable app store or is a certain game or app? If so what is it?VIA
