Writer Adam Hartung does not mince his words; his opening sentence about Ballmer reads: "Without a doubt, Mr. Ballmer is the worst CEO of a large publicly traded American company today."
As evidence, he cites the fact that Microsoft's stock has now fallen to a value in the low $US30s, from a high of $US60 in the year 2000.
Ballmer, he says, has singlehandedly been responsible for guiding Microsoft out of the biggest growing and most lucrative markets - mobile music, handsets and tablets.
Not just Microsoft, Hartung said, Ballmer had also endangered the fortunes of other companies like Dell, Nokia and HP which are part of the same ecosystem.
Windows Vista, the biggest screw-up by any technology company, was launched on Ballmer's watch.
Now, says Hartung, Ballmer has bet the company's entire future on one technology - Windows 8. And he says the future of HP, Dell and Nokia, not to mention a host of other companies, also rests on this decision.
