Re: Android wear
Good to her that the Sony Smart Watch 3 is working well... Sony actually had a connected watch years, but their first attempt didn't receive great reviews (would too often lose connection, apparently).
Another Sony gadget that makes some sense - and could be considered a 'wearable' - is their usb-stick-sized Bluetooth Headset. It can clip to your top like small MP3 players, and can be held to your ear to make calls or you can plug wired earphones into it, as you would a phone. It includes media controls, for playing back music from a phone, or can function as an FM radio independently of the phone. It also has a monochrome display for phone notifications. It makes sense for people with big phones, or for people whose phones live in the bottom of a bag.
I'm not recommending it here - you can find your own reviews - but I'm mentioning it because it is curious that so much coverage and discussion of 'wearables' omits devices like this.
