That's reaaaaaaal fancy. Engineering, pioneering, and bling factor aside, are these complicated systems really necessary for something so basic and simple as vaping?
Yes and no.
If you've use one of these "fancy" systems, you would know the immense difference. I suggest you go to a local vape meet in your area and see what all the fuss is about.
Vaping can be as simple as you want it to be...just like a cell phone. You can have something that calls and text only...or you can have one that has apps, works better, faster processor, and tells you the weather.
Does this mean that a smart phone is better than a flip phone from 10 years ago? Not neccesarily. Phones are technically suppose to be simple- make a call. Then they added texting, then apps, etc...does that mean a rotary phone from 30 years ago is a piece of crap? No...it means there is something more out there like a $500 IPhone or Galaxy Note- are they better? From a technical standpoint, yes. But if you've only used a house phone for the last 50 years and your comfortable with only using that as it gets the job done, to your own individual needs- it can be just as good to you, because you don't need nor want more...
So yes, want the most amazing vape of your life? Want flavor that is so full, round, and fulfulling it makes you want to "slap yo momma", with pillowing clouds and zero issues- then yes, it is necessary for a 100+ system...but if you don't need nor want better than be happy with your ProTank II or alike. It gets the job done. If you knew what you were missing, you would go for a better system.
Just like how I'm going to assume that is a DSLR in your pic. I'm going to take a leap and say it's a Cannon or Nikon.
Why? Because those are the best made even though there are other brands that are less expensive that people like and use everyday. Bet you aren't going to buy a Sigma $100 micro lens for shooting insects for the rest of your life when you know a $900 lens will do it better.
