VPN’s are a way of masking your address, sort of like caller id blocking for your internet: the sites you visit won’t know where you are logging in from or who you are, which allows you to be a later safer when surfing the web. It also allows travelers to access websites and services usually only available to them at home.
Take a look at PCWorld’s rundown of VPN services and I highly advise you to consider choosing one for your own use; if not on a daily basis I’m sure there are scenarios where it would benefit you to be a little safer on the web.
