I've travelled with my N810 a fair bit, crossing borders often, but much of the time, I've used it only for very time-sensitive things (carrying slides for a conference presentation, for instance).

The usage model of the N900 will extend my behaviour somewhat: there's much more space, more speed, and the capability to in fact carry around quite a bit of potentially sensitive information and use it sensibly whilst traveling, let alone at my desk.

There are 2 issues here:
1. The number one computer crime is laptop (device) theft, which can open up your information to all kinds of nice or nasty people
2. Crossing borders is becoming a sensitive issue, and the authorities can and may look at/copy your data. You may not mind, but do you trust them to destroy it, or send it to a competitor, or worse, use it against you or a client (if you're a lawyer, for instance)

When I carried a laptop, I was sensitive to this problem, often going to some lengths to ensure it was relatively 'clean'. A reasonable rule of thumb was never to carry anything you would regret either losing or having someone else see (or both).

Caveats: Passwords and encrypted data are not enough. Passwords can be coerced or bypassed, encryption is vulnerable. Also, this isn't just like losing a phone, there's a whole hell of a lot more possible here.

The problem now rears its head with the N900, I think. So:

Here are the questions:

- What kind of data do you carry in your device?
- Do you protect the data in your mobile device? How?
- Do you use any apps that might transfer to the N900? e.g. mobile or laptop-based data hiding?
- would you use an app that explicitly protected your data based on, for example, location, context, as well as id?

Reason: I'm working on a design of an app to work in this direction for my personal use, and wanted to see what people's thoughts were on their own usage.
