I agree.  This has been quite a bewildering discussion in many
ways.  One of the greatest things about free software distros is
the way we can keep old hardware running, and running *well*.  In
the process, we show that community development is less wasteful
than that of Microsoft et al.  They have their vested interest in
making people throw old but otherwise OK computers into landfill.

x86_64 for the performance seekers, x86 for everyone else.
What's not to like?
