My wife is not a techie person... but she does still really appreciate technology and she definitely lets me "do my thing" with gadgets. She actually watched the Apple Watch unveiling on AppleTV while I was at work so that she could talk to me about it that night. Cool lady
I bought her the first gen iPad (when I bought one for myself as well)... but it just didn't stick. She went back to her Macbook instead. She now has a Macbook Air and still has no interest in an iPad.
Like the OP she is still using an iPhone 5S... and REALLY does not want one of the new bigger phones (I upgraded to a 6+ myself).
She doesn't want anything to do with an Apple Watch herself. Just says that she would rather have *other* jewelry instead!
That said, she does enjoy technology. We have a small, modern condo that we've tricked out with all kinds of gadgets. Our philosophy is, if it has to be so small then we can afford to stuff it full of cool stuff. Here's some of the gadgets we have:
1. All Hue lights everywhere. Hue Taps in all rooms to control them. (I'm really surprised, but my wife does pull out her iPhone and set individual lights the way she wants them if she's going to be in a room for a while!).
2. Nest thermostat (tied in with the lights... and the entertainment system)
3. Harmony Home Control on both TVs... tied in with the lights in each zone and Nest thermostat.
4. Automatically opening trash cans from Simple Human. Once you get used to them you'll never go back!
5. Withings smart body analyzer scale.
6. Simple Human automatic soap dispensers at both sinks (this is actually nicer than it sounds ;-)
7. Bluetooth speaker in the shower.
8. AppleTV's on both TVs (she loves that she can just dial up movies easily).
I'm really surprised... but my wife uses (and enjoys) all of this stuff. (Just to be clear... I'm surprised because she's not into technical stuff herself... not because she's a woman! I'm a nuclear engineer and I work with some of the smartest and most technical women on the planet... I definitely know that women can get down with tech just as much as dudes!)
She loves getting out her iPhone and using the Harmony app to click "Watch a Movie"... and the TV, receiver, Bluray player all come on and switch over automatically then the lighting is drawn down in the room automatically and the air conditioning is set to the perfect moving watching temperature (69 degrees according to my wife). She smiles every time ;-)
