First of all, thx BoldlyDubious for liking my idea.

Also, I have a new feature I want to suggest for this kind of device: secrecy protection.
Sometimes, documents are meant to be secret and not to be shown to unauthorized people, especially for documents that are carried by officials in government positions or some other private CEO level decision makers. So, I think a form of secrecy protection is needed, so they can carry the documents with them where ever they go, and the institutions hiring them, and the officials themselves, are free of concering other people who will sneak, and get their hands on those secret informations.

A very simple way of doing that, I think, is to provide password protection, to ask for password whenever the user is trying to power up, or wake up the device.

Another simple ways is to ask password, whenever people is trying to open a document.

Or, have security markups. To markup documents that are meant to be secretive. Documents with security markup will require password, while other documents are not.

If some people attempt to access a secretive document and fails, or aborts before successed (or try to do power up/wake up the device, but fails to enter a correct password, or aborts before a correct password is entered), a warning information will be logged. Which can be shown later to the authentic device owner. And when the device is WiFi connected, the warning log will be automatically sent to the insititutions who concerns the secrecy of the documents (maybe as an automatic email feature that emails to a specific mailbox dedicated to recieve such security warnings).

Thats all I can think for now.

Additonal Note: For secrecy objective, security password should be also required when device user is trying to connect the device to a computer, or try to connect the device to a wireless network (i.e. invoking Wifi), or anything which the user is trying to connect the device to the outside. And warnings will be logged whenever user fails to provide a correct password when he has to. (Also, microSD should be refused to handle security files (at least the user/institutions will be adviced not to put their secrecy files on microSD), or even if it handles on microSD, there should be some sort of security lock/encription etc on the secretive files, so secretive contents on microSD should not be able to viewed outside of this device.)
