The Ipod killer is called Nomad Zen

I don't know about "killer": although cheaper, it's substantially thicker and heavier and doesn't have the superb physical design, or (from the look of it) such a nice screen. But it does look like the first real Ipod competitor.

As of today I'd still buy an Ipod (though I'd get the 20Gb, not the 5 I currently have).
