Honestly, they don't appeal to me. I mean, number one, I'm not a nu-metal'er who plays spineless, one-finger, detuned power chords that needs an extra bass string to get a heavier sound.
I appreciate what guys like Vai are doing with the extra string, that is, simply increasing the range of guitar and letting themselves do more with it; but 6 strings is plenty for me thank you very much, and I'm not pretentious enough to want to simultaneously play the part of guitarist and bassist, which is what I hear a lot of guys and tryin' to do.
