Yeah, you gotta watch that bottled water is at least as good as tap water, and yeah my multi-filtered/conditioned/UV-sterilized/RO water tastes better (and is probably a *lot* closer to pure), but those bottles are very convenient; it's an easy way to always have water with you.
Heh heh, before somebody says "just fill up a bottle with your RO water..", sorry, I find it a hassle, especially cleaning the bottles (backwash and all, for one thing and lip-balm mess for another). Once you filter out all the chlorine, you have to be a bit careful. My wife refills bottles with RO, but I seldom do...and guess which one of us *always* has water with them
