If this is already possible, please tell me how. I have two android devices, and every time I look them up, I have to search for clues to see which is which.

I suppose there might be a way to set the hostname on the device itself, but it would be much more comfortable if I could do it on the PC, with a keyboard, using the Account Manager.

If it's not possible to change the host name remotely, perhaps a free-form info field could be added? So I could label one of the devices "cell phone" and the other "eReader".
