Return on Investment:
Research In Motion (RIMM
), the creator of the ubiquitous BlackBerry, is playing catch-up to the Apple iPad. Mike Lazaridis, co-founder and co-CEO, above, unveiled the company's answer to the iPad on Sept. 27: the BlackBerry Playbook, due to launch early next year. Although the stock market has responded positively to the announcement—sending RIM's share price up 30 percent to $63 as of Dec. 6—it's too early to tell whether the tablet will be as popular, or addictive, as those "CrackBerries."
