	Yuri Grebenkin's commments up-queue were well put.  My newest
	2800 AMD runs Ubuntu mostly for things-fun.  Tho it has evolution
	so I can just click-on a mail-embedded URL and have firefox come
	alive very easily.  No mouse swipe and messing with broswer in my
	default mutt.
	(&c.)  Not *quite* like running a server just to have vi or
	another editor handy, but close.  The Ubuntu runs my DVD/CD
	burner too.  ---But it's still what I consider a "toy."

	Every situation is unique, I think.  Are you admin'ing a slew of
	server?  are you running a few to several for a small business?
	Or just running two machines for your own fun and profit?  

	Some things to consider (besides powering -down or -off drives)
	are battery backup system.  Don't most UPS systems isolate your
	servers from the wall-socket?   At what level do hard drives have
	identical circuitry so that they can be software lower-voltaged?
	*Except for consumer __cost__*, why don't all boxes have builtin
	batteries like latop?  ...There are lots of things to consider.
