I don't have to unlock it nearly enough as I do for an iPhone. I probably unlock my iPhone 50x more than I do an iPad (this is not an exaggeration). After all, you always carry around your phone and you are always unlocking to check messages or phone calls or emails. With the iPad, once I unlock it, it is pretty much on for the entire length of my browsing or content consuming session. Unless I get distracted and it goes to sleep mode. Is there a chance that the iPad will never get the Touch ID? I just don't see a point. I also think Apple might not incorporate it in order to distinguish the iPad and iPhone lines.
