I was travelling to BKK recently. The Thai customs document explicitly calls out computers as items to be declared and to be taken through the red zone.

Now, normally I'd just assume this was something that would be ignored, as I've been through lot s of countries and no one has ever cared about a laptop in the last couple of years on entry. I had some extra time, however, so I declared my laptop and proceeded, for the first time in a l-o-n-g time to the red zone.

The Thai customs people listened to my explanation about why I was distracting them from their conversation, took my form, and then they basically told me to beat it.

I'm revising my personal rule of thumb on gaming Customs so that, except in Canada or German speaking countries, it's not worth declaring a laptop. (Of course, this guidance doesn't apply to Russia, anyplace in Africa, or, generally, any place you have to pay dash to get things done.)

So, if the Austrian customs instructions explicitly call out laptops, flip a coin about declaring it. It may be that the red line is short and they'll just shoo you away.

Of course, if your number has come up and the inspector has to make some "stats," you're hosed anyway, so advice for the general case might be worthless on the micro level.
