I rarely travel with a laptop but when I do, or my boys do, I can’t be bothered with the security hassle so I put in it my suitcase. Despite my case being well and truly abused my laptop has never suffered any harm. As a precaution I do remove the battery though.
Concerning security of data. Luckily it’s never been lost and while I do carry some sensitive data I keep this on a memory stick (triple encrypted) rather than the laptop itself. For less sensitive data I keep it on a cloud server based in Switzerland and everything else such as my pickled onion recipes is kept on One Drive.
I’m not sure however I see the point of this ban. If you’re coming from say Yemen intent on doing harm, then you fly to another airport not affected by the ban and then fly on from there?
The way we’re going we’ll soon be back to pen and paper and all traveling on ships again!
