Adam Hartung:

Without a doubt, Mr. Ballmer is the worst CEO of a large publicly traded American company today. Not only has he singlehandedly steered Microsoft out of some of the fastest growing and most lucrative tech markets (mobile music, handsets and tablets) but in the process he has sacrificed the growth and profits of not only his company but “ecosystem” companies such as Dell, Hewlett Packard and even Nokia. The reach of his bad leadership has extended far beyond Microsoft when it comes to destroying shareholder value – and jobs.

As I said a year ago, he needs to be gone.
