The Zen Stone comes with 1GB and 2GB storage, while for a few quid more the better value Stone Plus has FM radio, voice recording, a stopwatch and clock and equalizer. And there's now a new 4GB model alongside the existing 2GB one.

The Zen Stones play WMA, MP3 and Audible formats, but again the Plus model comes up trumps with the addition of AAC support playback of iTunes tracks - arguably a more important upgrade than the speaker.
And fitness fanatics can buy one of those sporty-looking armbands separately.
The Zen Stone will retail in the States for $50 (£25); the Plus for about $60 (£30). As before, the players come in a range of garish hues as well as conventional white and black.
Hopefully this doesn't mean the end of headphones, otherwise we'll all have to put up with Bloc Party on the bus to work.
