BlackBerry’s Grip on Enterprises May Be Slipping Shares in Research In Motion took a hit on Wall Street Friday due to investors’ concerns that enterprises are starting to look to other mobile platforms. Dell’s 25,000 employees are abandoning RIM’s BlackBerry, and several major financial institutions are rumored to be considering a similar switch. BlackBerry remains a formidable player in the enterprise market with assets and an installed base it can leverage, but the company needs to make some big investments to close the circle in its enterprise strategy, noted Al Hilwa, director of applications-development software at IDC.
