Opera launched a Cross Platform Mobile App Store, which is a repository of Apps across various Phone Platforms.  Currently the supported platforms are – Android, Blackberry, Palm, Symbian and Windows Mobile. iOS is conspicuous by absence, but probably there may be links soon back to the Apple Store.

I think it is pretty cool for the following reasons:

• It is a Web App.  Pretty easy to use on any device with a Browser and supported Platform, nothing to install
• Can build an Ecosystem of Developers to market their Apps, across various Platforms
• Centralized Billing for Apps on multiple platforms – usually helpful if you own multiple devices on Android, Blackberry etc.
• Huge scope for tracking the Statistics on Apps usage and popularity across platforms

I can’t do much with the Store, as I just have an iPhone and nothing else.  But this is surely an App Store to keep our eyes on.
