Which applies also to USB hard drives. Mine sometimes keeps spinning for a day until I notice.

Seems to be something related to Unix as a whole, or maybe it's only Microsoft Windows that turns of USB devices after unmount? Mac OS X has the same behaviour as Linux.

I'm a iPod user, and this isn't a good idea for this users, because I unmount the iPod but the iPod still charging, and I like this situation

this should be made as an option, not just power off and thats it.

You can spin off external hard drive with the command :
sudo sdparm --command=stop /dev/sd[x]

Then spinning off should be done by default after gui unmount.

I voted up...then remembered my iPod. I like to unmount and leave it charging.

I think there are more USB key users than iPod users...
And as mentioned previously, it could be made optional.
Or even simpler: Right-click and choose between unmount and eject. (eject causing the light to go off of course)

@KIAaze: optional is a god idea, and turn off by default.
maybe an option when unmount an iPod, a question to stay alive or turn off is a possibility.

What if you have more than one partition? What if you want to unmount just to change mount point and remount inmediately?
Perhaps it could be better to have a "stop device" option.
As for the Windows reference up there, when you click on "Eject hardware" in Windows, you are not umounting anything, you are just stopping a device in order to remove it. You click on this or that disc or card, but the system traverses up the device tree until it finds an ejectable node and stops that, effectively stopping everything else under that branch in the tree.
