Yes? I'm a USian living in the UK, so I've got 2 "active" credit cards and 2 "active" bank accounts. When I get my monthly statement, I take 2-3 minutes to skim through the transactions. That's 10-15 minutes per month. Given that a bogus transaction could be in the thousands, I think that's a sensible precaution. In addition to catching any unexpected transactions, it gives me a quick overview of how much I've spent this month and on what, so I can maybe factor that in to how much I spend in the next month.

And it's a heck of a lot less time than I spend on HackerNews. :-D
