I understand, but disagree with this approach. In my experience, there
are times where switches are beneficial. For example; If an interface
fails, in a back to back config, both links drop and you can't easily
tell which node is faulty. Secondly, many managed switches offer
features that are appealing, like bandwidth monitoring, cable
diagnostics, etc.
