Had one for a while. I managed to install it in place of the stock CD unit so its tucked away. Upgraded to an 80gb disc so pretty much all the music I own is on it.
Very handy as I no longer need to even think about which CDs to take on journeys etc.
Browsing for particular albums/songs is okay. You can browse by artist name, album name or genre.
If you hold hold down the browse button in albums for example, it runs through the content via the alphabet. A.....B...C...etc speaking the letters vocally.
You can edit the setup files on the disc so it can read track details the way you like it. Album, artist, track, or just artist track etc etc.
You can change the voice to a number of different styles, woman, man accents etc. See the phathack website.
You can random play an album or your whole collection.
