I know that ABeautifulPlaceInThe is right, yet I use precious few of his recommendations. It's an effort vs risk assessment for me. I change my passwords a lot more often though and I do use a VPN on public networks.

I think that ABeautifulPlaceInThe may suffer from professional deformation (I hope this Dutch expression translates well to English) but most people will simply not be as aware or worried.

If I had a ton of highly sensitive information on my laptop I would certainly ask advice from an expert though.
