I haven't seen one yet, but there's the new quad-core R-Pi to
consider, too. The thing about all the ARM stuff is that the
software has only been in developement for a couple years. PC's
on the other hand, have been running *nix bigtime, since the
'70s-'80s. The original Arpanet goes back to what, the 1950s?
There's no getting around the fact that ARM is good stuff,
but they're playing catchup.
