That was what I thought when they offered me the new switch design, but it only took a couple days use to realize that you just simply don't need that long of a draw to get a lungfull, and in fact more than 5 seconds is very difficult with this vapor level.
Besides, the switch resets its clock in a tenth the time as a regular switch, so a barely noticable pause does the trick and you can go for another 5 secs if your lungs can handle it.
Not to ,ention, can you imagine if you were told before trying e-cigs fpr the first time that you'd have to drag on them for 6-7 seconds? That's a deal breaker for most new users, so making that unnecessary is better, IMO. After all, in the end the goal is to help people switch..
