- Yes. I've seen lots of Macs that display the Finder menu bar while in

- <chuckle> I've seen quite a few cases where the surge-suppressor/power
- conditioner/UPS has caused more problems than it's solved. On the flip side,
- I've seen a lot of burned power supplies after power glitches too.

- I think you'll find the main reason power conditioners aren't built into
- equipment is size & weight. A good power conditioner, even for a PC, is an
- extra box that you don't want adding to the size of a desktop system. In
- a large system, it's more economical to have one cabinet full of power
- conditioner than to duplicate the thing for each component, even if the
- individual parts are smaller. Power conditioners tend to be brute-force
- devices, relying on lots of copper or big capacitors (or both) to keep
- transients at bay. The last one I had much to do with weighed over a ton.
- It was serious hard work for four or five of us to shift with crowbars and
- jacks.
-
- As for surge suppressors, I have one of these little $5 button arrangements
- "protecting" things here; I don't know if it does any good, but it doesn't
- do any harm.
