You have a Windows phone? Or you mean you’ve put the Edge App (I mean I’m already scared that exists) on your phone?
Anyway, I have to use Edge a fair bit, either because I’m testing out websites where I don’t have the cookies in place from my normal Chrome/Firefox browsing, or because work has some shitty stuff you need Edge for.
Faxes are still in use for some businesses meaning you send them documents via a virtual fax machine software thing.
I really hated faxes when I worked in places that used them. Just achingly slow and then there was the obligatory phone call after to check whether they actually had received everything okay, plus the little print receipt to file away (even though it would probably have faded to nothing in a few months).
