Do you actually use the dongle? It doesn't work with inline mics, making it useless even if you were to carry it around everywhere. It also doesn't work with previous iPhones, so you can't share say a car aux between an old and a new iPhone.
Is this a new thing? I haven't used this in a while, but the lightning dongle used to work fine with my headphones+mic (also intended for Apple's headphone jack). I know there's some difference in how the headphone connector is set up between Apple and everyone else though.
I don't really have any strong feelings either way about it. I dropped my phone once, and the dongle took the brunt of it (saving the expensive stuff) but I did have to buy another.
