I go back to this argument: Why exactly do we need this device. Aside from the fact it's cool technology, I'm still wondering if you have a laptop or netbook and if you have smartphone/iPhone, I'm still not clear why you need this. And how many of us can afford to have a phone, a laptop, netbook and tablet/iPad? Do we really need a device for every situation?
