I have 3 jobs. I work in the IT dept of a very well known Gun manufacturing plant, so something to put in the lunch box not in the pocket. I work for the local school and college driving a bus there again something to put in the lunch box. Then I do photography for special events and weddings in the afternoons and weekends and teach photograhy classes for senior citizens center and photo clubs.
So, you sure don't get a lot of sitting down vaping relaxing time. You're going to be "vaping on breaks." You don't sit at computer all day and if you do, you probably don't vape at your desk. So you don't need a pass thru.
You will always need a backup. Most people's *first* kit gets relagated to backup when they move up to more expensive PVs. So, I agree with Madjay. Two Ego Twists (I always buy joyetech) 650mAh (shorter than the 1000s but you could certainly buy 1000s which are longer and better bat life but not as portable) and a mini-vivi nova and/or some cartos. You can't go WRONG with that purchase. You will use them.
I dunno about Provari for you except for home. Unless you do not worry about having a $200 item stolen, or leaving behind lunch box. There are cheaper tube mods that others can advise you on, that can take a beating, you can ding them and bump them and not care that they are rattling around in lunch pail on the school bus.
However, YOU might also want to consider a holster for your your more expensive PV. You can wear on your belt like a cell phone or beeper and it will always be on your person.

I don't think you're the type who is going to be floored by techie stuff like changing settings, looking at little windows, etc. I don't even think you'll be changing stuff out much. I think you are BUSY. You want to carry something w/decent battery life, and batteries that you can take in and out so that you can carry extra batteries with you (in a battery case.) when you can't be near a charger. (Ego batteries will have to be placed out of use since they go on the charger and you cant use them).
So, egos with a carrying case: AltSmoke.com | Personal Vaporizers | Electronic Cigarette | Ecigs | eGo Carrying Case - Small, Medium, Large
and then some kind of tube mod... in a holster or in lunchbox. If you feel comfortable taking a Provari out and about, then buy it.
