Tube mods have hit their wall: Using good, cheap batteries was the main thing they could accomplish. Now they can regulate the voltage of the batteries they accommodate and give us a rough idea of how much battery life is left. What else do we want from a battery holder? The next steps in PVs are in these two areas:
1) Atomizers that last longer: This may be akin to anyone in the late 80s and early 90s who that "The tire companies are holding something back, there is a rubber tire that lasts forever". Anyway, an atomizer that lasts six months or a year or a lifetime... That's something to shoot for.
2) juice. I think this is the main thing that needs improving. Two base liquids have defined e-cigs since they began: PG and VG. I'm looking forward to the next base.
