I dunno. They've (more or less) embraced web standards, made overtures to the OSS community with a bunch of commits to the linux kernel, and have generally been a whole lot less monopolistic. Granted, Ballmer may want to be Gates and lack the ability, but the end result is a far less scary beast.
The commits to the kernel were to make it run in their VM, even if you consider that a good thing (I'd say it's neither good nor bad) the patents they're claiming to hold on Linux, and the patronising language they use in connection with that, about people making use of their innovation is as evil as anything they used to get up to.
