Bit by bit, device by device, the family are using iOS. They didn't take up Linux when I forced it on them, and I've refused to deal with their plethora of Windows issues that cropped up so often it almost became a full time job. The girl uses an Air, the lad has my old MBP - it's just the wife and her "Jen from IT Crowd" possessed laptop to go. In the last ten years I've had one - ONE - Mac issue. A failed screen on the iMac and they replaced it FOC even though it was out of warranty. No viruses, no worms, no slowing down, no freezing, no locking, no conflicts, no lost data...nothing. I can't say that about any Windows device that has ever existed in this house.
