Luckily I work with quite a few computer geeks who smoke, all of them 'love technology' and wanted to know more information. Some just wanted a excuse to try and get a rise out of their managers, while others are actually trying to cut back/quit.
I've shown the
device around to a lot of people and they all give the same response. Typically saying, 'WoW.' after i puff on it. 'What??' after I go through my spiel and showing them how it works. And then 'How much?' after the end. But I'm very upfront with everyone warning them about the cartridges, informing them of the risks and the lack thereof studies.
Some people accept this while others will pass, but I sleep better knowing that the ones that do want to buy one, understand exactly what they are buying.
