I've got the 8GB version of this and love it, this 12GB version is on pre-order at Play for only £49.99 which is actualy cheaper than the 8GB version everywhere else!! It's available at Currys for £89.99 so this looks like a great price!
They are fantastic little players with great battery life and the best thing about them is that they take micro-SDHC cards so for another £10-12 you could make this a 20GB MP3 player for only £60!!!
Plays videos, music, photos and audio books
Digital FM radio
Up to 24 hours for audio playback and 5 hours of video playback with internal rechargeable battery**
MicroSD/microSDHC slot for additional content expansion
Videos (MPEG-4) Music (MP3,WMA, secure WMA and audio book file formats), Photos (JPEG).
Play all day with 24 hours of battery life and room for up to 3000 songs. The new Sansa Fuze from SanDisk is your portable music machine with 12GB of storage. Watch video on a 1.9" screen, share photos, jam to FM radio, and play with the sound recorder. Long battery life in a thin device. The Sansa Fuze marks the next wave of music & video players.
CAUTION: Some people have suggested this may be the 8GB player with a 4GB card included, have emailed Sansa to confirm if they do a 12GB version! If it is the 8GB then it's still the best price for it at the moment from what i can see.
UPDATE: Sansa have confirmed that this will be a bundled card to take it up to 12GB. NOT a 12GB player. However even the 4GB player on its own is the same price as this which will either be 4GB player + 8GB card or 8GB player + 4GB card, still a bargain!
