Reading the small print on packaging and asking it to repeat the bit you missed feels like a concrete everyday use. I especially like the idea of asking follow-up questions aloud instead of hearing everything again. Describing what's in front of you is a different task from helping you move safely, though. Google explicitly warns against using it for navigation or obstacle detection, so I'd keep this to checking information while standing still.
