For me it's basically pushed the US far down the list of places to go for leisure. I see the risks as still being very small, but why take the risk when there are so many other great places to visit too?

US immigrations stands out for the least pleasant experiences I've had on entering a country, and that includes entering places like China, despite most of the time being perfectly fine (I used to fly in/out of SFO every 6-8 weeks for a period of about two years, so I got to compare them a lot).

For business, I will still go if necessary, but I'm finding that I'd take the same precautions for the US as I did for China: Make extra sure to have a full, recent backup, and move "everything" off my laptop onto online storage, just in case they decide to seize it.
