Electronics aside, I still get entry stamps in the the USA every time (passport from Denmark).
In my last two passports I also had visas for studying/working in the USA.
Travelling to the USA for pleasure became much simpler when that last passport expired - no more arguing with check-in agents about whether I was travelling on visa waiver or on the visa (visa not expired, but also not valid, as I was no longer living in the USA), and no more lengthy questioning from CBP about how you go from working for The National Institute of Aerospace on an H1-B visa to teaching high school. It was kind of messy until a CBP agent at Philly took a black marker to the H1-B visa "CWP".

But I do like the stamps - still remember fondly the first US entry stamp from a Canadian airport. I found it hilarious at the time.
