Have any data to back up that the iWatch is inaccurate? Or that the iWatch will be a major gimmick (what is a major gimmick? Aren't gimmicks decidedly minor by definition?)?
Nope. I'm just assuming that a small jack of all trades will be less accurate than a larger, dedicated device. Besides, when we've added on all the 'extras' such as the watch and blood pressure band/monitor etc, it's hardly a miniturised piece of kit anymore is it? Who is going to carry all that around with them on a daily basis....and who needs to? This is solving a problem which doesn't exist. Did you ever think about buying the products which already exist in the marketplace to carry out these tasks? You're just jumping aboard an idea because Apple deems it time to do so.
