A lot, apparently, if you live in Sparta!
So, if you were too lazy to read the link, here’s the story in a nutshell: A man in Sparta has been parking out in front of a coffee shop to piggyback off the wireless Internet that is provided to customers. Doesn’t seem like a big deal, eh? Yeah, until you find out that Michigan could fine you $10,000, and throw you in prison for five years. Yikes.
CNN actually has a video up on its web site right now about this story (see it while you can). It’s provides a pretty balanced look at whether those people who don’t bother to secure their Wi-Fi connections are either morons or victims. I’m going with the former, personally.
