An extension of my original question, now that I finally ordered the NB is ... does anyone pump in their car on lunch break? I work at a large institution and have no private office so was hoping to get some pump time at lunch. This is all theoretical until I've used it anyway. 
Also how critical is the airlock?
Thanks

I would advise against doing it in the car during your lunch break, unless you come to work in an RV or something. Most company parking lots have video monitoring these days, so unless you want to risk ending up the next Internet sensation you probably don't want to do this. I would just do it at home and not in the car at all. Driving has enough distractions and dangers without worrying about your breast suction process as well.
