Well, that's why you wind up buying an extra atomizer, and, if you're smart, you also pick up a different model with some backup parts. (You generally pick a different model not only because it's nice to have a different type of vape, but if it becomes difficult to find parts for your other device, the thought is that you might be able to find parts for the other model.)
I do think you'll like the 510. By the time you start to think about maybe yet another model on top of that, the JantyStick and PureSmoker Prodigy will hopefully have been out long enough that there will be a fair number of reviews.
I'm assuming you've ordered some liquid for your e-cigs, right? I can't remember if it's been discussed in this thread (and I'm too lazy to go back and review it), but imo it's pretty much a necessity. Cartridges just don't last very long, and it's wonderful to be able to top them off with liquid. The difference in the amount and quality of vapor between a full cartridge and a half-full one is staggering. Plus, the 510 is a liquid monster, using lots of liquid to produce beautiful, billowing clouds of vapor.
One more bit of advice . . . if you find yourself enjoying the 510 (which I think you will), please pick up some spare parts. As you'll learn soon enough, atomizers can last a couple of months . . . or crap out within a couple of weeks (and sometimes days). There are few things more frustrating than vaping with your last atomizer and having a hard time finding a spare . . . or worse yet, killing your last atomizer and not having a spare on hand. I personally recommend at least 2 spare atomizers, 2 spare batteries (or a USB passthrough), and an extra charger. For the 510, it's easy enough to do by simply purchasing an additional set for parts.
