My first reaction was definitely one of ‘wow’ – the interface is slick, and a quick phone call to their ‘test service’ (didn’t want to wake anyone!) revealed the call quality to be excellent, although it seemed that a little part of my test message was dropped.

Only problem I can see with it is the lack of cell network support, I’d really like to be able to make calls on the go without having Wi-Fi nearby. Other ‘nice to have’ would be the use of background processing on the iPhone, but that is Apples’ fault obviously. Maybe push notifications could be used somehow in this app? We shall wait and see…
