Another reason to hate "soft touch" power switches

And based on that point, soft touch power switching is unnecessary.

What about the supposed "can't let a hard power switch abruptly interrupt power or you'll corrupt internal data storage?" A power strip would risk that every single time.

Uh. Just because you use a power strip doesn't mean you shouldn't first switch off the device with its soft button. It just prevents any of the annoyances that were first mentioned, such as having it spuriously restart or having it draw current (however little) when in the soft "off" state when you're not in the lab.

A traditional hard switch delivers all of those advantages automatically.

So far, I'm not hearing much that favors soft touch switches over hard contacts. ATE perhaps, but otherwise not. (I mentioned rack mount but most rack mount equipment isn't power cycled that much anyway, they often don't even HAVE a power switch.)

   I plug everything into outlet strips then I KNOW that it's turned off! This part of the US is prone to a lot of lightning strikes so turning everything completely off is a necessity.  Surge protection built into the outlets is an added benefit.

There's a lot to be said for the power strip concept - including that it completely bypasses any soft switches, in which case the soft switches are completely unnecessary, which was my original point!
