VPN services are not usually free, but there are affordable options, from temporary/timed to continuous. They have the additional advantage of thwarting the use of so called '
supercookies' which are increasingly stalking both smart phone and home computer users.
This thread has been very enlightening.
I never access any critical sites, such as banking, from anywhere except home and I'm only a periodic user of public wifi away from home (hotels, airports). Even then I keep my usage to a minimum. However, I don't care for the idea of someone reading private emails.
It would be interesting to hear more about VPNs from our members about their experiences with them…what they've used, what they they liked/didn't like about particular ones, et cetera.
