In the run-up to IFA 2014, Motorola's invitation alluded to four separate devices. There were two smartphones, which we now know to be the Moto G and Moto X, as well as the Moto 360 smartwatch. The other, rather more mysterious item in the teaser was an earpiece, which has today been unveiled as the Moto Hint. It's not only tiny, unassuming and stylish, but it works as an all-in-one digital assistant, and while the wearables market is currently littered with head-mounted devices and watches very much like the Moto 360, this interesting product has certainly caught our attention.
