Totally agree. The idea seems to be a good one, but the fact that it's limited to iOS and using the old connector is a big letdown.
Something like this takes a long time to develop - you may find that development started well before Apple announced the new port style
Which is why it seems to make more sense to use a standard USB connector. (I forget the legalities of shipping things with an iPhone connector included, but I remember there being a hubbub about it.)
Which is one of the reasons to avoid proprietary connectors like the plague.
