I see MS as the same they've always been. The open specification that
they have for their document formats they've tried to change already
because they don't follow it themselves. The recent open source code
they gave to the Linux kernel was only given because they were obliged
to, as they'd used GPL'd code themselves, and the GPL required their
resulting code to be given back to the community.
In the area of web standards, well, as any web developer knows, it's an
absolute mess at the moment, with each version of their browser behaving
completely differently, and even IE8 has only just caught up to where
other browsers have been for a long time. As such, I can't see them
supporting much (anything?) beyond what Windows Media Player will
support by default.
