Actually, the rumor is that Microsoft might be in the market to purchase Canadian-based mobile device manufacturer RIM (Research in Motion), makers of the popular Blackberry communication devices. Microsoft may be feeling some pressure to stake a stronger presence in the mobile device market after their two biggest rivals have entered the fray. Apple recently rolled out the iPhone through AT&T (formerly Cingular), and Google is reportedly seeking to purchase airwave bandwidth and may be announcing a Google-centric mobile device of their own. Microsoft already makes the Windows Mobile operating system, used on a variety of mobile and handheld devices. The purchase, if it happens, would put Microsoft in a position to develop both the hardware and software, and could also allow them to potentially phase out the Blackberry OS, one of the biggest competitors for mobile device operating systems.
