Still somone else's computer
yes, "the cloud" _IS_ highly overrated!
For businesses, I remember this really cool thing that came out back in the 90's - it was called "a web server". The best ones run Linux or BSD. It's a fair bet that setting up a file sharing system with one of THOSE, even one that involves user names and passwords, wouldn't be all THAT hard...
/me wonders if excessive Win-10-nic use has dumbed down the users into believing that it MUST be "in the cloud" ???
