Airflow or not, there is vapor getting in there. None of us, or should I say most of us, (there's always one) are not going to go into our computers, (laptop or desktop) and take a ph strip or something like that and run tests in a lab to see if its coating our processors and memory and other important bits on our mother board. But Id bet a buck it is and it's not good.
Then look at us when we smoked cigarettes. We did our best to keep it clean, but Im sure if one was to take a q-tip and wipe it on important areas we would find a nice thick coating of yellow nic and ashes etc.
Only way we can safeguard our machines is to have filter pads or a large clean room set up. Wear those "bunny suits" and not bring anything in where we have our computers.
Like everything, Im sure in a few years someone will release the outcome of some study and have us panicking about something vape related.
Someday we might get a ticketed for impairing our sight while driving. We will see anti vaping ads similar to the anti texting while driving.
Use your better judgement and be logical.
Am I going to vape while I use my computer? YES... If I didnt then Id either not ever be able to use my computer or never have time to vape
Am I replacing all my carpet and clothing ? NO
Am I not going to wear "fragrances" or sneeze or.....etc.
