Yes, Halloween was yesterday, but creepiness doesn't fall on a particular day.

It is creepy that third parties can use your smartphone or PDA to keep tabs on where you are. In some jurisdictions, with the proper authorization, the system can compel your service provider to provide access to your call activity logs, SMS messages (which are archived in your provider's servers for a significant amount of time), and even telephone conversations.

Let's also not forget your location. Gadgets with built-in GPS do have very important uses, like helping emergency services locate people in trouble. But, it can also be abused by those who have no business knowing where you are.

As we get more connected to each other, there's always a chance that someone will take advantage of those connections to our detriment. That's creepy.
