Motorola Droid :: Using Pattern Lock Or Other Security On Phone?

I'm seeing so many people complaining about the new lock screen that it seems that many Droid owners aren't using a pattern lock to secure their phone. This really surprises me, the phone contains access to all your email, contacts, calendar, and any other personal data you may have placed on it, and a large percentage of you aren't even using the basic security provided by the pattern lock? Or is it that many people don't know the pattern lock exists? I just can't imagine having a phone like this that isn't secured to whatever extent is available.
