Not Miss: Former Yahoo CEO Carol "F-Bomb" BartzThere's a reason Bartz got her walking papers over the telephone. Really, who would want to deliver the news to her face? The fiery Bartz is \n\nknown for tongue lashings and f-bombs that would make sailors cringe. While her straight-shooting talk made Yahoo look scrappy, her phone call \n\nfiring makes Yahoo look spineless, too.\n\nBartz Couldn't Deliver Yahoo Turnaround\nCarol Bartz Out As Yahoo CEO\nWith Bartz Out, Yahoo Must Refocus or Die\n\n\nMiss: Former Apple CEO Steve Jobs, Super Control FreakWhen Jobs retired as CEO last month and the media spun story after story, you'd have thought the iPocalypse was upon us. Jobs has been billed \n\nas the greatest visionary CEO on the planet, but we contend it'll be his control-freak nature that will be most missed at Apple. Jobs was best when he \n\nwas saying no to extraneous features, no to products that weren't ready, no to pesky reporters... \n\nCIO.com Teardown: Apple CEO Steve Jobs\nSteve Jobs at Apple: In Pictures\nApple's Greatest Hits Under Steve Jobs\n\nNot Miss: HP CEO Leo Apotheker, a.k.a. The Cut ManNobody misses the hatchet man, especially one as spectacular as Apotheker. In less than a year as Hewlett-Packard CEO, Apotheker has managed \n\nto turn the iconic Silicon Valley company into a wreck with a dubious future. HP took a bath with its failed TouchPad, and Apotheker plans to spin off \n\nthe PC unit. Heads are rolling. Even if HP comes out of this okay, Apotheker has spent his leadership capital.\n\nHP CEO Surprise: Former SAP Chief Apotheker Takes Charge\nHP Plans PC Spinoff, $10 Billion Autonomy Buy\n7 Ways to Use HP Touchpads After They Stop Working\nWhy You Shouldn't Buy a Discounted TouchPad Tablet\n\n\nMiss: Facebook CEO Mark Zuckerberg, Geek with a Dark SidePowerful you've become, Mark, the dark side we sense in you. Anyone who has seen the movie "The Social Network" knows of Zuckerberg's \n\ngenius and cutthroat tactics. He's a feared leader, a legend in the making. It's ironic that the social networking king has some of the worst social skills \n\nof any CEO. Then again, you don't have to "like" him. Likeability is an overrated CEO trait.\n\nCIO.com Teardown: Facebook CEO Mark Zuckerberg\n\nNot Miss: Microsoft CEO Steve "Wild Man" BallmerThe famous video of Ballmer hopping around on stage maniacally \n\nchanting "Developers!" cemented Microsoft's image as a company that's losing it. Who can take this guy seriously? Ballmer comes off as hyperactive \n\nand too focused on sales and marketing. And marketers can be the most untrustworthy of the corporate lot. Good leaders come off a little more -- \n\nheck, a lot more -- controlled. Put another way: Would you want to follow this guy?\nCIO.com Teardown: Microsoft CEO Steve Ballmer\n\nMiss: Former Google CEO Eric "Cool Hand" SchmidtContrast Steve Ballmer's outrageous style with Schmidt's cool demeanor. When Schmidt talks, you get the feeling you're listening to your wise \n\nolder brother, intelligent yet approachable. Google replaced its steady hand with founder Larry Page, who, with his wind-blown hair and casual dress, \n\nplays the younger brother perfectly.\n\nNew Google CEO Sweeps in With Company Reorg\nVisiting the Googleplex\n\n\nNot Miss: RIM Co-CEOs Jim Balsillie and Mike Lazaridis -- Who's the Boss?When things are going great, people will praise even a committee of so-called leaders. It really doesn't matter who's in charge. But when \n\nchallenges arise, there can be only one who steps up and carries the company on his or her shoulders. This is where RIM's Co-CEO structure has \n\nfailed. Risk-taking. Accountability. Consequence. You can't divvy them up. Otherwise, it's just a sitcom.\n\nCEO Teardown: BlackBerry-Maker RIM's Mike Lazaridis and Jim Balsillie\n\nMiss: Oracle CEO Larry Ellison, a.k.a. Bruce WayneDoes anyone know who's the boss at Oracle? Hint: There's only one. Ellison's shadow looms so large that many Oracle executives left to run \n\nother companies: Tom Siebel, Craig Conway, Marc Benioff, Zach Nelson. It was Ellison who won the database wars of the 1990s and built an empire. \n\nIn those days, rumor had it that there was a bat cave under his Japanese-styled samurai home.\n\nCIO.com Teardown: Oracle CEO Larry Ellison\nLarry Ellison in Pictures: It's Good to Be The King\n\n\nNot Miss: AOL CEO Tim Armstrong, Dazed and ConfusedEarlier this year, someone leaked an internal memo about "The AOL Way" under Armstrong's watch. The document details the relationship \n\nbetween content and profitability that flies in the face of journalism, sending mixed messages about AOL and its services. Now there's finger-pointing \n\nand yelling coming from TechCrunch founder Michael Arrington. Confused? Yeah, so are we.\n\n\n\nMiss: The Fall of Former HP CEO Mark HurdIt's a pretty good bet Hewlett-Packard misses Hurd these days. Last summer, Hurd resigned as HP CEO following an investigation into a claim of \n\nsexual harassment (which found he hadn't actually violated sexual harassment policy) and falsified expense reports. HP hired Leo Apotheker, and \n\nthings have gone down hill. Couldn't Hurd have blamed it all on damn autocorrect?\n\nMark Hurd's HP Dismissal: 5 Unsolved Mysteries\nMark Hurd: a Look Back At His HP Tenure\n\nThe Best of 'Damn You, Autocorrect'
