"Unlike other companies, Microsoft never developed a true system for innovation." Dick Brass, a former VP at Microsoft, lays out in a scathing NYT op/ed how the company has destroyed its ability to "bring us the future." It's insanely fascinating.
His anecdotes, from this time running the Tablet PC division at Microsoft—you know, the kind of computer that Bill Gates believed was the future—are chilling, revealing the destructive level of competition between some divisions. For instance, someone in his group developed ClearType, Microsoft's font smoothing tech that was developed to sell ebooks, but other groups at Microsoft freaked out and actively sabotaged the project, or tried to steal it from the tablet division, which is why it took 10 years to actually make it out into the world.
