iOS is getting close to being all the computer my grandparents could ever need. My mother as well. My father and I are both in tech and would run into too many hard (and fairly artificial) limitations pretty quickly.

I won't ever switch my primary computer to something that needs an optional accessory to hold the screen up. ipad may be magical, but there is plenty of wonder left in a device can open up and start typing on a real keyboard immediately. It's been many years since my primary computer has been a desktop, but I'm not willing to compromise on the permanently attached keyboard and freedom to decide what executes.
