That's it, although I've not had Vita brand water.
It's a hell of a lot easier getting it out of these bottles than an actual coconut. If you find you like it, I think you'll be fine sacrificing a little authenticity for convenience.
Most of the companies that sell the stuff are all New Wave so you shouldn't have to worry about preservatives and such, but check the label if it concerns you.
I suggest you try it flavored as well (mango). If you hate it plain, you're probably not going to like it flavored, and it's hardly the nectar of the Gods that you need to get down your throat somehow, but the flavored still has the coconut water taste...just less pronounced.
