Research in Motion will soon launch an online store to rival Apple's, with Nokia and Microsoft to follow

Businessweek reports...

On Apr. 1, Mike Lazaridis, co-CEO of Research in Motion (RIMM), is expected to take the stage at the wireless industry's annual trade show in Las Vegas and open the virtual doors to a much anticipated new online store. BlackBerry App World will be chock-full of software programs created by outside developers that visitors will be able to download to their RIM phones.

It's the first of several major assaults by rivals on Apple (AAPL)'s fast-­growing iPhone business. Apple has stoked demand for the device by offering thousands of software applications from independent developers through its App Store. Now, Nokia (NOK), Microsoft (MSFT), and Palm (PALM) plan to follow RIM with virtual software stores of their own this year. "There's going to be a significant counter-­challenge to Apple," says Mike McGuire, analyst with researcher Gartner (IT).

Nokia, RIM, and others sell more phones than Apple. But Apple has leapt out to an early lead in transforming the mobile phone into a sophisticated computing device onto which people load their favorite software. The number of mobile phones that can browse the Web and handle other advanced tasks is expected to surge from 139 million last year to 295 million in 2010, according to Gartner. These so-called smartphones are on track to eclipse the 300 million-unit ­personal computer market. "This could make the PC wars of the 1980s look like small potatoes," says Trip Hawkins, chief executive of mobile game maker Digital Chocolate.
