I've been thinking about this and I can't get my head around it: apple are going to preview iOS 8 at WWDC in June. One of (if not the biggest) feature so far is looking to be healthbook. Now the iWatch is scheduled for release in September - the device that Healthbook is actually made for. So how are they going to preview iOS 8 without an iWatch? There may be features of healthbook that use only the iPhone to operate. But even so, wouldn't it be 'giving the game away' as to what's to come with the iWatch? Just interested to hear your thoughts.
