Sorry ZH875, but you are (ahem) "misinformed"
The main reason there were so few problems is that a lot of people spent a lot of time preparing for it and mitigating it.
"The total cost of the work done in preparation for Y2K is estimated at over US$300 billion ($407 billion in 2014 US dollars).
IDC calculated that the U.S. spent an estimated $134 billion ($182 billion) preparing for Y2K, and another $13 billion ($18 billion) fixing problems in 2000 and 2001.
Worldwide, $308 billion ($418 billion) was estimated to have been spent on Y2K remediation."
(just wait until 2038 turns round!)
