Ipad mini and vpn

I have ordered an ipad mini. I doubt I will use it on public wifi very often. But from what I have read , if I do , I shoud use a VPN. Do not know a lot about it. Did read that there is a VPN included but that it is not a very good one. But , I believe it said there were others available from the app store.
Do you know anything about ipads and vpns?

From what I understand there is at least 2 reason for using a VPN - to connect to a network on a remote site and for security. I would only be using it for security.
