@6 - You mean draining the phone's battery? The Bluetooth uses some power of course, but I haven't seen a noticeable difference in my phone's battery life since adding the watch. Is yours draining faster?
@7 - I had a somewhat similar reaction when I tried it in the store, but it's totally different wearing it all day. It's not meant to be "exciting" exactly, and in some ways the opposite. You play with it because it's new, but after a bit it starts to fade away, which is where I've seen the real potential. It's not made for sustained or deep interactions but for very quick ones. Paraphrasing Matt Gemmell from his excellent review
, it's the first device I've had that seems to encourage me to use it less
