Another board with a "so's your momma" vibe, but I'll weigh in with something more thoughtful. Don't over-think this one - it's Blackberry redux - i.e., a founder who has it in his head that he deserves 10 or 20 mill a year has been raping every other shareholder for years. Siri was and is a kind of bad joke, and there's no real moat around the product/company - i.e., look for a fistful of better mousetraps in the months and years ahead.
Icahn has a mixed record re tech ... and for every Apple with an amazing "second act," there are a dozen who stubbed their toe, got gangrene and died. This is a company that's "aged" far more poorly than Microsoft, and I'll guess that Icahn's bench is thinner than thin, so look for his "boy" to be ignored until Carl starts jumping on the table. But as was the case with Blackberry, that was nothing more than noise, since the company had been hollowed out years ago. Again - same situation here - the people who said Blackberry was another Palm were right, ... and this one is yet another "has been." ... Much better to go with the "wannabes," because tech stocks whose best years are 5 or more years back are like week-old fish in the fridge - meriting being tossed.
