because their windows xp is pirated

stoled from ships?

Of course, I've already dropped FIrefox's power consumption significantly using Adblock, Noscript and so on

I think IE don't beat that...

you don't need a virus scanner in windows and even if you have one it probably won't save you anyway... hardened IE security settings and disabling of plugins should be sufficient unless you're into warez and porn, and if you're dumb enough to click on links in unsolicited email you deserve a good infection

Say that to average Joe user :-)

And same company would have to pay additional admins to troubleshoot security problems.

And magic ones, that don't consume power to work! :P

I haven't used IE in ages, as there is no Linux version so can't even try it.

Its my case too (and, I think, of various people here)

And the people I work with keep moving the dam stapler!

It's a common problem here!

I fail to see how using IE over the other major browsers yields a net saving. Power usage is only one factor.

how much are you losing elsewhere in lost productivity, insecurity, virus infestations, etc, because you are using IE

IT support contractors are doing quite nicely

They don't user power! Oh, wait: it's not possible...
