Issue 26 of the Microsoft Windows Platform News included an interesting link
that describes Microsoft's current policy/plans for product lifecycle
support:
<http://support.microsoft.com/default.aspx?scid=fh;[LN];lifecycle>
This information may be useful in planning your own product's ongoing
support. (As well as to get a clue as to when development tool support will
expire...).
