Most nerds I know (including sysadms) started out on Android because of all the reasons you’d expect. Most of them now use iOS / iPadOS because, at home, they want things to Just Work - and have the available income to throw at the problem. Desktop-wise many of them have used Macs on and off, but it seems like lately they trend Windows and Linux again. Probably because macOS has become more hassle than it’s worth with the continued locking down, increased paranoia, lower flexibility and ridiculous storage prices. It used to be that you could work around the storage prices, but these days it’s practically impossible to run programs from somewhere other than Applications if you want your system to stay up to date. Macs just aren’t the great *nix alternative that they used to be, and while Windows is still pretty awful for my use, Linux as a desktop/gaming system is getting better every day. At least so far. I miss when macOS became more useful for every release. The big releases these days break more than they fix for me.
