The iPad Air 2 is my only device. It's my personal and work laptop. It's also my cell phone thanks to LTE connectivity and my number being ported to google voice. I take it with me every where every day. It would be wonderful if the Apple Watch connected to the iPad because despite my love for it, the iPad is not always convenient to pull out. Meanwhile there is almost no situation where you couldn't pull out the iPhone. In fact, from what I understand, there are many people who had returned their watch because it's literally easier to pull out their phones. Smart watches could be more useful for those of us who want/need a remote because of their atypical use of tablets and laptops. How does it hurt Apple to include us? I can't imagine there are enormous numbers of people who would ditch the iPhone to go my weird route so iPhone sales wouldn't take a hit and any limit in functionality would hurt the buyer (who knew what they were getting into) not the seller. My dream scenario is either the iPad gaining access to the Apple Watch as it stands or a 4G Apple Watch that connects to any device. As for why/how the Air 2 is my only device? I carry a pack everywhere and I only make about 4 calls a week. The rest is data.
