Ok, here goes.
Original iPad Air with mobile connectivity. Handed down from my husband, whom I graduated to a “Baby Pro”.
It’s my reading / sofa/ travelling/ navigating/ camping/ entertainment/ carry-anywhere device (an original 12.9 Pro stays firmly anchored to a flat surface at home). It’s also the device I take to the office as my mobile “bible”.
I keep it on iOS 9 so I can troubleshoot and guide an octogenarian family member, living 2 countries and over a thousand miles away, whose only computing device is an iPad 2 with a ceiling of iOS 7 as it’s operating system (oh the joy of grouped notificafions in iOS 9!).
2nd generation iPod Touch. Carries all my music and is used exclusively for that purpose, mostly on long journeys. This was my very first Apple device.
At the office, our technical staff have iPad 2s in daily use as their digital notebooks, calculators, niche engineering apps, etc. We’ve had to replace the Apple covers but the devices soldier on.
Also at the office my old iPhone 4, used to make calls to mobiles and receive support phone calls, as well as to work with our technician when he’s doing vehicle installations of our equipment.
