I'm not sure what servers you're talking about here.

If by server you mean one of those things in a rack at Amazon or Google or Rackspace - power consumption, and its consequence, cooling - is *the* major issue these days.  Also, the servers used in such data centers don't have multiple free USB inputs - they may not have any.

If by server you mean some quite low-power box in someone's home ... power is again an issue.  People want these things small, fan-free, and dead reliable.  And they are increasingly aware of the electric bills always-on devices produce.

About the only "server" for which power is not an issue is one of those extra-large desktops that small businesses use.
