It was recently announced that the there are now 100,000 apps made specifically for the iPad in Apple’s App Store, and there are 500,000+ apps available to iOS users.

On the opposite side of the numbers spectrum, Microsoft just hit 25,000 apps in its own Windows Phone Marketplace. Sounds like there’s still a lot of catching up to do…

It’s important to keep in mind that Microsoft managed this number in only 5 months of the WP7 Marketplace being open to developers. At that type of acceleration, Microsoft is on track for a pretty successful Marketplace in the near future.

Engadget points out that,

“The main point is that the WP7 ecosystem is growing, and faster than previously at that — it took until the end of March to accrue 11,500 apps, a span of five months from its launch, whereas the last 13.5k have come in the brisker period of three months.”

Sales for Windows Phone 7 haven’t exactly been booming, but don’t count Microsoft’s mobile prodigy out just yet. Perhaps a partnership with Nokia will turn the tide?

Numbers aren’t necessarily everything when it comes to these types of figures. It’s a known fact that 80% of the apps in the iPhone’s App Store are pretty bad. Quality will always supersede quantity.

Microsoft could continue to do well with smaller numbers in its Marketplace, as long as larger companies and developers are supporting the WP7 OS. If famous titles like Angry Birds are available on Microsoft’s platform, that could be enough for the typical consumer to buy into the ecosystem.

What are your thoughts? Does Microsoft’s Marketplace stand a change against the App Store?
