I actually like the idea of refillable pods with a battery unit one can reuse. Not sure I would use such a device but do appreciate the notion of it. Like
@f1r3b1rd says, why toss a whole car if all you need is a new tire? The totally disposable ones I don't care to see. Again though, that's only mho.
And if honest, in a way when I used the ARO type clearomizers and eGo styled batteries, I did use a refillable pod system. IRRC, these clearomizers only held about 2 ml, or 1.5 ml.
Here's an ARO style atomizer.
Here's an eGo style battery.
These do well, okay but they don't satisfy me. I went to using squonking which holds from 7 to 10 ml depending on the device. I also RDAs where I can use a larger diameter coil. I can also replace coils, wick, swap out batteries and recharge them. Still after a few years your batteries wear to not taking a charge. Then you need to recycle them properly, buy fresh batteries. But you're not throwing out whole devices, not unless of course one goes terribly bad.
