If anything the trend has already swung back, with the Juul and many similar devices using nic salts. Convenience stores appear to carry a better selection of small non-cigalike devices than they used to. Some of the older devices are no longer produced, of course.
Atomizers with high capacity are very clean running compared to old school devices. Avail was taken to court for selling EVOD/Protank devices (low power) due to their high rate of aldehyde production. I don't know if that was in normal use but wouldn't be surprised, and other tests have shown the nasty chemicals output are worse by percent for them, even if it is tolerable. I liked them, but didn't completely switch until I also had something a little higher output (and a diff. set of juices for it).
As well as the wide variety of pod systems, the respected Aspire nautilus line of tanks has been expanded on, as well as the original still being sold. I did have to go back to the shop I bought mine at for new coils, but they plan on carrying them for a long time and they still sell.
