In their efforts of providing a useful and informative experience, Nokia is adding some new items to their Ovi Store that should ultimately help guide users in their app searching experience. When browsing the Ovi Store's long listing of apps, the noticeable changes includes content you're browsing will have some clearer information, a change from a three to five star rating system, and specifics on which devices are most suitable for an app. It's assumed that Nokia decided to go with the new 5 star rating system to follow closely to what's seen on Amazon and iTunes – it's not clear how they'll modify the current ratings on apps for the new transition. The worse thing that can happen is for a user to download an app that's not suitable for their handset – let's say a game intended to run on an N97 will be experienced differently on an E75. So apps that are reviewed will now note on the page which handset was used for the app. Although these may seem like minor additions, it does go a long way in becoming more in tune to offering the best experience for the user.
