The other thing I would encourage is MIPS-based platforms for routing
devices. There are a number of options on the market already, some with
quite a number of GbE network ports built in.

It is fairly weak; there hasn't been a lot of push to create stronger
alternatives that still respect the owner's rights. The POWER systems
are the only real option on the high end, leaving middle-ground users
(including higher-end laptop users) without any options. This probably
won't change for a while due to razor-thin margins in the mid-range
arena and lack of overall demand.
That all being said, there are some stronger ARM Chromebooks coming down
the line this year. Google Oak is one platform to watch; the SoC used
in those machines gives you ARM64 plus virtualization, but sadly that
machine is not yet available to the public.

You're correct, and we're not advocating that people dump their existing
machines, only that this is considered when purchasing another machine.
What I personally would like to see is the major FOSS projects and
distros starting to think beyond x86, perhaps by compiling and testing
their software on ARM / POWER as well as x86, even if they are
continuing to develop on older x86 machines for the time being. In the
case of router distributions (pfSense comes to mind) the developers
should start focusing on providing (at minimum) an ARM or MIPS port;
this would also have the bonus of lowering the power consumption of the
As you say, the current Opteron 4xxx/6xxx series devices are currently
adequate for most work. The danger is complacency; 5 - 10 years from
now those chips will be wholly inadequate for many common tasks and
there may be no way to upgrade in performance without also sacrificing
I should also point out that all recent AMD chips, including the
upcoming Zen Opteron CPUs and the modern FX-series devices, require
signed binary blobs to boot. They are not free and, worse, by design,
they can never be freed. AMD has also refused to release any
documentation on the A1200 series devices, and it is highly likely they
will also require a signed TrustZone binary to boot.
