Here's a quote from that article that makes me leary of the idea:
"Some experts warn that such technology isn't a security cure-all. For instance, blasting private data from lost or stolen PCs won't protect companies from theft by disgruntled employees looking for payback. Others say the tools could make it too easy for information to be accidentally removed: "I can see a situation where, if the controls are too stringent, one executive is going to get his laptop hosed because he's been in Malaysia for three weeks inspecting factories," says Andrew Jaquith, a security analyst at the Yankee Group, a technology research firm in Boston. "It takes one mistake to make a piece of software like this very unattractive."
Others ask, what happens when an absent-minded employee simply forgets his password? "I have had mornings where I couldn't remember one of my 13 or 14 passwords -- and I've tried several times," said Stephen Northcutt, a researcher at the SANS Institute, a computer-security research and training organization in Bethesda, Md. "
But to address Closet_Nerd's question - if you've lived in a system for a while you'll have a bunch of data that you wouldn't want strangers getting. It doesn't have to be all that exotic. Online banking details for example, or if you've ever sent a request to a company to email you a replacement password because you've lost yours etc. can be the kind of thing you don't want strangers to get a hold of.
