2. Sony S2 Sports Network Walkman NW-S23: Pity poor Sony. It invented the Walkman and then squabbled as Apple stole its lunch. This player finally supports MP3 files, yet it lacks so much else that it’s hardly worth the price. With ergonomics straight from a Klingon warship, balky software, and a poor display, this one deserves a place in the remainder rack. Again, you’re better off with a shuffle.
