Hey thanks to the group for all the responses on this query.
I used to leave the slug running without switching it off initially though started to see some odd behavior on my USB thumb drives connected to it. They used to occasionally refuse to work unless I shutdown and waited till the system cooled off (though admittedly this is probably more the thumb drive at fault than the slug). The slug is well ventilated but given I'm living close to the equator, its pretty hot here in general. So was playing it safe.
The reasoning about power up/down causing a strain on the components makes sense of course. I think I'll give it a try leaving it on for a couple of weeks straight and see how it goes.
Thanks all!

Subject: [nslu2-linux] slug - power down or leave on 24/7
Leave the slug always powered on.
It only uses 7 watts so there is little electrical cost. When pc's cost $4000 in the '90's you would leave them always on as the cost of electricity was less than the cost of replacing the pc. Now, with pc's only a few hundred dollars and using over 100 watts in many cases it makes sense to turn them off when not used.
When I buy a new electrical device (tv,etc.) I will turn it on/off(unplug) daily+ for a month+ to "burn" it in and see if there are infant failures on components before the return/warranty expires.
What is hard on components is the heating up and cooling down of these devices. This is why most failures occur to electrical components.
I used to work at a company where we would do testing and burn-in testing of chips and most component failures occur right away and then level off over time. Burning in components involves heating/cooling/ humidity/ no humidity to components to simulate years of stress on the components.
