Android: If you're unable to read your Android device's screen, either temporarily (while driving) or permanently, the free Talking RSS Reader can jump into your Google Reader account and read the news to you in a synthesised voice.
There's very little that gets in the way of the program's operation, as the only controls are hitting the Menu button to access your Reader feed list, scrolling up or down to find a place to pick up reading, and hitting Back or Forward to move between feed items. The voice is a fairly standard, slightly advanced Speak & Read-type tone, but it's not too hard on the ears if you're listening to feeds while tackling other tasks. If you were really busy, it might be a good way to keep up on heavy Twitter users, or even email feeds if you can grab them.
Talking RSS Reader is a free download for Android devices only.
