Incorrect values: 4 times as big and 8 times as heavy - but
the same power consumption. :-)

Don't confuse my use of "network terminal" with classic serial
terminals. Look, for example, at the devices AXEL builds, or
already present for many years: Sun Ray terminals. They also
have audio I/O, card reader, and USB connectors (where the
keyboard and mouse usually are connected). A regular monitor
(maybe with speakers) makes it a full-featured workstation.
But no data users can mess around with, and its power requirements
are really low.

Our university's library had many of them, and I liked them
because they were completely silent (in difference to the
boring beige PC boxes they scattered around the library).

You can find specs of an AXEL terminal as exemple here:

	http://www.axel.com/usa2/prod_ax3.html?mv2_pos=1

They're calling it "thin client", but it's terminal. A box
where you plug in a screen and a keyboard and connect it
to a network IS a terminal. :-)

Today's average users are treating their high-end HPC PCs
as worse typewriters, so there are enough cycles to use. :-)

Which is no problem using network terminals, everything you need
is a LAN (or maybe even WLAN) connection.

Still, multiple GPUs is possible, but results in a major raise
of power consumption (because you have to use a "modern" GPU).
Multiple input devices is no problem via USB.

ARM is an efficient platform in terms of energy, and I think
it will be more and more important in the future, especially
if you consider the mobile devices market. And when it's good
at running on battery, it's good on running on AC power. When
the industry comes up with "extra new energy efficient PC
hardware", we already know that it existed for years. :-)

Hey, 640 kB should be enough for everyone. :-)

That's what they want to make you believe. :-)

By using means of blocking for known script-kiddie sources, you
can get rid of a lot of useless traffic - and possible trouble.
