My intention was not to criticize cigalikes in general or Blu in particular. You are absolutely correct to point out that those products have introduced people to vaping and ultimately therefore allowed them to quit smoking.
But if Big Tobacco becomes the primary player in the vaping industry, there will be a conflict of interest: Big Tobacco's meat and potatoes is still on the cigarette side of the business. So you cannot count on Big Tobacco to innovate on the e-cig side. What you can count on from Big Tobacco is that they'll make e-cig products that are only as good as the market situation dictates they must be. You can count on pricing that allows cigarettes to compare favorably.
Big Tobacco, in other words, is a reluctant participant in the e-cig market. They must remain relevant, so they'll throw their hat in the ring, but will they cry if the FDA imposes a massive tax that increases the price of e-cigs across the board? No. How about crushing regulatory requirements that will bury smaller operations in years worth of red tape? Hell no.
Blu isn't a terrible product, but it could be much better. Given the resources available to Lorillard Tobacco (and their ilk), you'd expect that they could produce an e-cig that'd knock our socks off, but they haven't. Will they in the future? All I'm saying is, "Don't hold your breath." Right now, BT can basically corner the e-cig market just by default; they have access to enviable product placement in basically every store in the country. And because their e-cigs are more visible to the public than superior products, those products have done a fair amount of good, basically by default.
