I only scanned the thread so hopefully I won't be simply repeating what someone has already said.
My wife and I are in our 60s and quit smoking just 3 weeks ago with the helps of e-cigs - in that time we've turned several of our friends onto e-cigs. Several have been - actually most of them have been liddle ole ladies who can't figure out the remotes on their TVs or how to surf the web, so it has to be simple. Here are my thoughts and I hope they're helpful:
If she's trying to quit smoking, I can't see replacing the habit with something that looks just like a cigarette. For me at least, that doesn't compute. I'd suggest one of the nice little Joyetech 510s with a refillable cart. You might start her out on the prefills, but being able to control the nic dose plus the flavor is a great plus in my book so steer her toward refillables.
We just bought a birthday present for a friend who has tried everything to quit. We bought her a Joye eGo passthrough with a Vivo tank. It took her a day or two to get the hang of it and I'm still helping her out a little. But she loves it and has already bought two more for friends! You need to explain that this is not a smoking device but an electronic instrument. Just like a smart phone or a TV remote, it requires a bit of practice. Encourage her to practice and get used to it. Be there for her, the first few days.
I made an instruction sheet that seems to be helpful...first I photographed the eGo in its assembled state, then I photographed it disassembled with the parts laid out side by side. Using a graphics editing program (Corel), I labeled the parts A, B, C, D, etc. This made it easy for her to refer back to the photo to identify the parts when reading the instruction sheet which I wrote. I wrote it as if I was writing for a first-grader - not because she's dumb but because she's a newby.
This seems to have worked out well, as she has only called me one time with a question about how to hook up the charger.
It's a shame that the eGo's and other devices don't come with detailed instructions. Many of the folks who really need to quit smoking are oldsters like me, and if the thing is confusing, they just throw it away or stick it in a drawer. I think one of the biggest markets could be older folks who are desperately trying to save money. Many of us have smoked for 50 or 60 years, and for many of us this could be a godsend!
I'm going to be working on my little pamphlet and offering it to my local vaporista, maybe in trade for a spare battery or two.
