The website and the first 5 minutes of the keynote fails to convey what the device does exactly, other than that it meant to replace smartphones, which can't be right. This form factor would be inconvenient for watching videos and that's one of the most common uses of smartphones. They should just market it as a pocket assistant and make it do one thing exceptionally well. It's a losing strategy to try to be everything for everyone instead of just trying to dominate a small beachhead market. Smartphones with better assistants are coming, but there is no reason to compete with them. Just differentiate the damn product.
