To be clear - I do not disagree. OneDrive sucks and Microsoft is a greedy piece of shit company.
However, do you think he would be better off with Linux? Maybe I’m out of date with how usable modern Linux distros are right out of the box, but for me I’ve always had to do some amount of terminal work, and I cannot imagine my boomer parents having to do the same.
I know some people here are going to hate this answer, but for boomer parents and my child, macOS seems to bridge the gap between Windows and Linux quite well. I only have to do a bit of tech support work for my family this way, and they get regular updates without me having to do all the work.
I don’t understand. A 5.56mm round has a .223 bullet. .223 is the caliber and is in inches already, no math required. .223 / 100 =0.00223 which isn’t particularly useful.
