Shares of Research In Motion finally stopped their slide on rumors that the company may be ripe for a takeover by Microsoft, Apple or another suitor. But that optimism was offset by news that the company has slashed its internal sales estimates for the PlayBook, which is the first RIM device to run its new QNX operating system. As the Wall Street Journal notes, RIM’s co-CEOs haven’t shown any interest in selling and they remain committed to their unusual front-office structure. So you shouldn’t be surprised if RIM shares continue to plunge in the near future.
