Well, I think MS expects the customers to move to XP, the current
version of NT.  Take RedHat.  I got a nice four year run out of RH6.2
with good errata/security support.  Now they have reduced support to
one year after release (unless you want to pony up for the enterprise
edition, then you get five years :).  They are ending all support for
everything before RH9 by the end of this year, and RH9 ends 30Apr04!
They claim that certain "popular" releases may be supported for a
longer period but AFAIK none have been identified as yet.

OpenBSD is supported for two releases, so that's one year also.

To me, one of the key points about an OS is how well the package
management system works and how much time is going to be spent keeping
the system current with the errata.  I can understand why it's
necessary to drop support on older releases, but how easy is it to
upgrade to the next release and then keep it patched?  Right now too
much time is spent with mergemaster grovelling over /etc.  Why should
I have to merge passwd and group files because a system user or group
was added at the new release?  Why not have separate files for system
and user?

Most Windows users don't upgrade, they just buy a new computer.
Most RH users seem to re-install rather than attempt an upgrade
across a major release.  With BSD and Debian, there's hope.
