FF, I tried the MIOX this past weekend. We were a party of four with one filter and one MIOX. It was definitely easier and quicker than filtering, but it's a hundred and thirty bucks, and it's battery powered, two major drawbacks. The major advantage over drops is that the MIOX is EPA approved. The Katadyn tablets are as well, but I'll tell you, those tablets leave a serious chlorine taste, and the MIOX does not.
I haven't tried the Aqua Mira drops, can someone chime in and comment on the chlorine taste? I know it's not a huge big deal, but I much prefer my pure mountain water taste like pure mountain water.
