What are your thoughts on Online Banking?

I like to use online banking, but I have reservations regarding its security. I have heard news about people being scammed or snatched with a lot of money from their bank accounts. They even say that the said misfortune had happened when they enrolled in online banking. In my case, I don't engage in this one since my bank is just on the other side of the road, and all I have to do is to walk. Again, I like online banking, but I'm hesitant to enroll in such service.
