Nokia's just announced at its Mobile World Congress presentation that, lo and behold, the company's launching its own online app and media portal, the Ovi Store. Download, Mosh, widgets are going to be focuses of the Ovi Store. The N97 will be the first device to be "pre-integrated" with Ovi Store, but "tons" of existing S40 and S60 customers will be able to download the service starting in May. The company says it'll learn your tastes over time and anticipate what you want, as well as make recommendations based on your geographical location. A developer site has launched, and is touting a 70% revenue share, which appears to match what Apple's doing with its respective app store.
