I'm presently using 21st Century cartomizer pv - oversized analog look, about 120mm long, 8mm thick. I'm presently smoking about 10 RYO analogs a day, down from 38. I bought the kit from the local Circle K because the smoke in the car was just getting to be too awful with two smokers and one non-smoker. Since then, the car has become a 24/7 non-smoking zone.
Things I don't like about them: It looks like an analog. I've had it accidentally trigger putting it into my pocket, and would much rather have a manual system. No blank cartomizers available (though I'm on the ninth refill of one of the starter cartomizers and haven't touched my stock of them.)
Things I love about them: Apparently, from reading on here, I've got some phenomenal battery life going out of these things. I can use it all day and into the evening before running out of power, and most frequently run out of juice first. I like the vapor production - not huge clouds of vapor (which does have it's appeal), but a very good mouthful which helps curve the urge for an analog.
In the way of an upgrade, I can see two very distinct paths - home use and portable use.
For portable use, I'd like to try to stay within the 120mm overall length, though thicker base is fine. Judging from YouTube style videos, I think I'm looking for a high resistance cartomizer with low-medium vapor production. I'd very much like to keep it 'stealthy' in that there's minimal lights, bells, whistles - mostly because I don't need everyone to know how bloody addicted I am sometimes.
A stealth inhale is great, because if everyone realizes only half of my smoke breaks are to actually smoke cigarettes, I'm going to lose those breaks. 
For home use, I'm think I'm more towards the whole drip tip experimentation phase, and don't mind hitting the odd shaped mods.
A bit more background - I've been making RYO analogs for 6 years now, being extremely selective in finding my preference in tobacco flavor and filter style. If I was smoking over the counter boxed analogs, complete instant conversion to a PV would be extremely easy - those things are just horrid. Smoke breaks at work are breaks from an extremely tight time cycle environment, and are the most difficult to give up. But the PV I'm using now has allowed me to set those breaks to my choice, not my desperate need.
So I come to ask humbly for advice as to what to seek out -
