Wireless Security: WEP is dead?

I just got finished reading the article How to keep your wi-fi network safe. It basically states that WEP (Wireless Equivalent Protection) is outdated and very insecure.

I’m not a security expert, but most wireless networks I come across either have NO security or 64 bit WEP. I probably run into about 30 or more business and organizations that have wireless networks a month, and I’ve only come across one that had WPA encryption.

How safe are we? I will attempt to break my own key in a lab with the tools that find off of google.

One more thing, if this is all true, why is WEP still offered in wireless routers and other equipment?
