for the pc architechture, this is certianly true. i would even bias
development toward 10 and 40gbe.
but for other platforms, i think 10/100 chipsets make a lot of sense
today. 10/100 is great for appliance-ish applications/
for example, this is a very interesting bit of hardware
(sorry, ron, mips, not arm)

an ethernet driver is here
https://dev.openwrt.org/browser/trunk/target/linux/atheros/patches-2.6.33/110-ar2313_ethernet.patch?rev=19906
it's a mere 1200 lines, which is just trivial in the linux world so if one
were to scare up documentation, it might be quite a dream to
program.
there were a few others i stumbled on recently. i recall reading
the datasheets for a few spi-based chipsets that looked pretty clean.
(obviously 10mbps.)
