"Well, I didn't want this to end in a discussion about what device with what batteries to get. We chose a Joyetech 510-T with automatic batteries, which I think is a device to like and to start with. And I hope that's what's going to happen"
I know that you didn't solicit advice on what to get, and don't seem to be inviting it, but please ponder this:
In light of your sentiments quoted above, which is better: a device that looks more like a cigarette but doesn't deliver as good an experience, or one that looks less exactly like a cigarette, but gives Auntie maximum enjoyment? To me, it's all about the hit, and far less about what the damn thing looks like. And I doubt that anyone is about to mistake a 510-T for an analog, are they? And are you really looking at a PV while you're using it?
Especially with older people, you might just get one shot at this. If the first experience isn't great, they might not give it another fair shot. I've never understood putting looks before performance and ease of use.

OK, before you write me off as an irredeemable jerk, I offer this in my defense:
Not being familiar with the 510-T, I went to Joyetech's website, and it seems to be screwed up, displaying the exact same pages for the 510 and the 510-T, leading me to beleieve that despite the nomenclature, the 510-T wasn't a tank system. (510-T(errific)? 510-T(op Notch)?
Exhibit A:

I just didn't want your Aunt to have to deal with crappy little cartridges, when tanks seem so much better. I've since read quite a few good things about the 510-T, and am more than convinced that you're on top of things. Cheers back at ya.
