There is a market speculation that Microsoft could be interested in buying Research in Motion, the BlackBerry maker.

"According to speculation, the software giant might be interested in RIM in response to Google's recent announcement that it is interested in making its own mobile phone operating system, which would compete with Windows Mobile," analyst said.

Research in Motion's ubiquitous BlackBerry smartphones have penetrated the professional market, but have yet to gain the same acceptance among retail consumers.

To change this, RIM has been loading up its devices with multimedia features like music players and cameras. It has also worked with carriers to make them more affordable to individuals.
