or "how to piss off a user because the developer thinks they know better"

modal behavior is evil, interrupting the user is a sin. never, ever get in the 
way of what the user is doing. if you must get in their way, only do so when 
they have explicitly said you may.

so i go back to: what is the actual real world failure we are attempting to 
fix? right now we have fixes for something that isn't, as far as we know, 
actually broken. and the fix introduces a new kind of broken.

yes. that doesn't justify interrupting the user or creating a modal state.

power management is generally perceived as part of the workspace. just like 
shutting down, restarting, etc are.

use case:

i walk away from my computer.
i forget it's not plugged in.
this dialog pops up when i'm not in the room.
result: event is ignored.

the event can and will be ignored. getting in my way while trying to prevent 
that is only going to piss me off (speaking as a user). in fact, it is 
probably MORE likely that i will just click it away to get at my work.

ok, another use case:

the dialog pops up.
i'm in the middle of a conversation.
if it's modal, i can only dismiss it to finish the conversation. so much for 
the computer helping me.

the dialog pops up.
i'm in the middle of a conversation.
it's not modal but it takes focus; i'm more likely to dismiss it quickly 
because it's "in my way". 
once again, the computer is not able to help me.

this is really basic usability: don't get in the way of the user, don't enter 
modal states. it will backfire if we try to run around that.

except for other things that may arise that are the same. *shrug* for most 
things in the notifications area, yes, it's different.

for the above reasons, i can't agree.

or just as likely they'll quickly get rid of the annoyance and forget.
or they will plug it in immediately cursing all the while about how the god-
damned computer keeps getting in their way.

and, because i'm in repetition mode already, where are the bug reports or user 
observation saying "i didn't notice that thing and so i lost data / time / 
something else bad"?
