HTTPS and VPN

Thanks for all the replies and explanations. I always thought that you were pretty safe using HTTPS, even on a public connection because everything is encrypted. I guess, as some of you mentioned, you're more safe using your own hotspot, such as cell phone, your own router, etc.

Edit: I was just investigating VPN's online and all the big nemes, such ax Nord, Express,PIA and others all offer strong encryption. So it would appear to me that usage of these VPN's on an unsecured network would provide good protection. Comments?
