Paul Allen has a memoir titled Idea Man coming out soon, and Vanity Fair just ran a spicy excerpt. Seems that the King of South Lake Union isn't pulling any punches when it comes to ratting out old friends and business associates. MSNBC explains:

Allen, 58, says he overheard a heated conversation between Gates and now Chief Executive Steve Ballmer in December 1982, shortly after Allen told them he was thinking of leaving the company.
"It was easy to get the gist of the conversation," writes Allen in the memoir as reproduced in Vanity Fair. "They were bemoaning my recent lack of production and discussing how they might dilute my Microsoft equity by issuing options to themselves and other shareholders. It was clear that they'd been thinking about this for some time."
Allen, who at that time was receiving treatment for Hodgkin's lymphoma cancer, and was scaling back his work at Microsoft, says he later received apologies from both Gates and Ballmer over the incident.

Bill Gates was a stone-cold Grinch-ass motherfucker.
