At £150 for just 1GB, the iRiver B20 can hardly be thought of as value for money. And we can't see why iRiver is charging so much for the 2GB, or 4GB versions when it is so much cheaper to add memory via the SD socket. Certainly with both Apple and Creative offering 8GB for £129, and Apple offering the 80GB iPod classic for the same amount, you'd really have to want DAB radio to invest in a iRiver B20. Still, the presence of DAB in such a portable form is impressive, it's just a shame that it's let down by a lack of storage space.
