The standard set up for a Plan 9 aficionado here seems to
be a Mac or Linux machine running Plan 9 from User Space
to get at sam, acme, and the other tools.  Rob, Ken, Dave, and I
use Macs as our desktop machines, but we're a bit of an exception.
Most Google engineers use Linux machines, and I know of
quite a few ex-Bell Labs people who are happy to be using
sam or acme on those machines.  My own setup is two
screens.  The first is a standard Mac desktop with non-Plan 9
apps and a handful of 9terms, and the second is a full-screen
acme for getting work done.  On Linux I do the same but the
first screen is a Linux desktop running rio (formerly dhog's 8½).
