Buzzvoice in public places.
Although I love my Android, I could do with a break from the screen in certain areas like buses, goup of friends and minimize walking into things on the streets (has happened to 2 of my friends), it could save someone from a world of pain -- LOL
All joking aside, I am very audio type person, I prefer podcasts to magazines for example. This would be a great add-on and (again) pretty non-obtrusive to anyone in my environment.
Thank you
