According to the BBC it will have a 20Gb hard drive, but store 3000 more songs than an iPod

Shame it doesn't support any music formats apart from Sonys propriatory system and is therefore doomed to failure. Why do Sony insist on trying to get light to bend their way? The number of "standards" they have tried and failed to create is endless:

Betamax
Memorystick
Minidisk
etc

And the screen on that walkman looks nasty

30 hour battery life is impressive though, as is the shock-resistant drive
