Well, people are too quick to jump on any stories blasting RIM nowadays. We should rename HN to "Questionable Hacker Rumors".
For one, it is a rumor. Apple Insider isn't exactly known for well placed sources inside RIM.
Second, even if we were to take this at face value, read the text: "The layoffs will affect the company's legal, marketing, sales, operations, and human resources divisions, a source said." Not that engineering isn't mentioned. That is a good cutting of cruft.
