But you're venting entirely from a sysadmin standpoint. The position
you advocate here nothing new; in fact it's common practice. Even in
the Linux world: have a look at RHAS or Debian "stable" - these things
are constantly on the verge of obsolescence (and that's being kind,
depending on when the last Debian release was ;).

Now think about it from a general user standpoint. "Sleep crashes my
powerbook." "My Xserve doesn't boot." Video drivers, SMP stability and
performance... Even getting away from hardware support, personally I
*require* the input layer, which allows me to plug and unplug USB mice
while also using a PS/2 nipplemouse without freaking out my X server.
It didn't always work like that. Wheelie-mouse support - it wasn't
always there! And now let's step away from the kernel: I'm sure you're
a diehard twm user, but I think we can all agree the KDE and Gnome
projects of today are much better than those from two years ago. And
anyone here who remembers trying to compile x86-developed code with
PowerPC glibc 1.99 will assure you that newer is better. :)

For many (most?) users, newer is better. If that weren't the case, then
what are all these developers *doing* anyways? :) As for sysadmins,
you're free (wise, even :)to keep doing what you've always done: if it
ain't broke don't fix it.
