While the claim has so far been uncorroborated, a takeover of RIM would greatly consolidate Microsoft's share of the smartphone business as it would own both hardware and software, contrasting with the company's historical approach of licensing Windows Mobile to multiple handset makers. In contrast to its control of the computer market, Microsoft has typically lagged well behind the BlackBerry line in the US and the Symbian OS used by Nokia, Sony-Ericsson, and other manufacturers on the world stage.

A takeover may also be an attempt by Microsoft to mimic its strategy for the Zune, where the company largely abandoned an attempt to create an industry-wide (but Windows-based) standard in favor of an integrated design similar to that of the iPod. No mention was made in the speculation of whether Apple's early success with the iPhone would play into a possible Microsoft bid for RIM, which recently began enjoying its own success with the advent of the BlackBerry Curve and Pearl media phones.
