Either your standard is to hardcode EVERYTHING or leave EVERYTHING Auto.

Many people espouse hardcoding infrastructure and servers, and
leaving desktops auto.

Auto-negotiation did not work 100% when it first came out which is why a lot
of places hard code the settings, but now it is not an issue any more.

Unfortunately, it -is- still an issue. There are still autonegotiation
failures, including some known to involve Cisco equipment.
(e.g., I seem to recall mixing Cat6500 + some 3COM switches is
a problem.) The failures these days -mostly- involve older equipment,
but "older" might mean in terms of design rather than manufacturing
date -- and there is still a lot of equipment in the field that was
manufactured several years ago. Also, I read about autonegotiation
failures involving some of the cheap consumer-level switches.
