I wear my watch on my inner wrist, where raise to wake doesn’t really work. I used to glance at my s3 dozens of times per day expecting to see the time or other information and seeing a black box. It was, by far, the most frustrating part of the AW experience.
Edit: let me expand on the above. IMO, one of the key functions of AW is to display information with maximum ease and convenience - the whole “I don’t have to take out my phone” thing. Yes, it’s also outright better than iPhone for certain things, namely health and fitness. But its ability to be your most readily-accessible screen is, for me, probably the most compelling reason to have an AW. AOD makes AW way, way better at being a ready source of information.
now that I have a s5,I’m blown away by how often I see other people’s earlier generation AWs sitting there as useless black squares.
