Paul Allen, quoted in Microsoft’s Odd Couple
describing Steve Ballmer.
Interesting article about the early years of Microsoft by its co founder Paul Allen, Microsoft’s Odd Couple, linked from slashdot, Microsoft's 'Cannibalistic Culture'. I also read the Isaacson biography of Jobs recently. The major similarity between Jobs and Gates is that they are/were complete and total bastards willing to screw their friends/partners for just a little more money/power.
