firstly I don't have money to burn so I have to think carefully before investing in new gadgets. My fear is this. Lifespan of iPhones and iPads are probably three years as iOS and apps evolve. Traditionally expensive watches could be expected to last many many years. The current iwatch could be virtually obsolete relatively quickly making it a hell of an expensive device. Don't get me wrong, I'd love one but finding it hard to justify 5 or 600 hundred euros for a watch with a short lifespan. Example, will current watch even function with an iPhone on say iOS 11
