do you have the computer set to sleep after one minute of inactivity
(the shortest setting)? if not, then you can't reasonably expect the
computer to be telepathic and figure out what the user really meant
when s/he removed the usb device. if it stays awake because energy

Are you really defending that a user might actually mean "wake up" when
they remove a USB device? Removing a monitor or ethernet cable doesn't
wake up the computer. Why wouldn't users want these to mean wake up?

they might, but removing ethernet or video doesn't *require* a wake
event.

It's completely obvious to me that this is just a side effect of the USB
spec, not an intentional user interface feature. It makes no sense that
Apple would purposely treat USB differently from other types of device
connections.

i don't know enough about the inner workings of usb to know if there's
a technical reason or not, but it's part of the usb spec and apple is
in compliance with it.
