There are so many things to like about the iPhone and I think many will agree one of the most important features is the App Store. Apple’s App Store has proven to be wildly popular and offers up all sorts of software and games that add fun and functionality to the iPhone.

With the success of the App Store, it’s no surprise that many other phone makers are looking to start their own similar store. Google has done it for its Android smartphones and now Microsoft has announced a new Windows Marketplace for Mobile to do the same thing.

Microsoft throws a couple interesting wrinkles into the model that Apple built though. First, you can download applications via the store (when it launches) and pay for the apps via your credit card or have them charged directly to your phone bill. Users can also return any application purchased within 24 hours for a full refund. That means if you hate that game you spent $10 on, you can get your money back. I wish Apple offered that.
