I've heard good things about this USB device: http://www.crypto-stick.org/ and am trying to have a bunch of them at the Kernel Summit this year to hand out to people if they want one. There are also lots of other smart-card form-factor devices that can be used to store GPG keys. Some places to purchase these can be found at links from the above site. thanks, greg k-h
