You can get microsd cards and even nanosd card that are so small that hiding somewhere on your person is easy.

Encrypt everything you need on it.

They are, should it be required, easy to quickly and discreetly swallow as a last resort. (To get rid of it. I have no idea what would happen to a nano sd card travelling through your body, but I presume that it, or at least the ability to read the data on it, would be destroyed.

Then carry a regular laptop with you, with all the regular applications and regular behavior of them. Boring.

Using tails as the main operating system on a computer you fear might be inspected by customs or secret agents is screaming:

"I have something to hide and you cant find it"
