HDB 630 quick review and questions

Quick review: Good, worth the hype.

Questions:

1. My single tap to pause/unpause doesn't work? I'm on an iPhone, and both bluetooth and BTD 700 dongle exhibit the same bevahiour.

2. Why's there so much lag? Watching yootoob vidya, even with the dongle is quite annoying, since the lips move quicker than the audio. I've never been very sensitive to this before.
