I think this thread has gone slightly astray.

The initial comparison was of a "ISP grade" router in 1991, to an
"ISP Grade" router in 2009.  There is no firm definition of this,
so I can't put my finger on a single definition that would include
or exclude boxes.

That said, the "home routers" being discussed are not something a
business needing GigE service would purchase.  They are not something
an ISP offering managed CPE to a GigE customer would purchase.  Be
it filtering, routing protocols, command line management, ssh, there
are a host of features missing.

I think it is quite cool that these low cost, specialized application
devices exist.  I'm not sure how this furthers the discussion of
device growth related to bandwidth over time.
