The Ipod's only advantage over the Rio Riot was form factor. That was enough.

But in that case, they were both "big disk" portables. So in that case, the form factor was the only major difference between the iPod and the Riot. (I don't know what, if any, price difference there was between the iPod and the Riot?)

In the case of Slate vs. iPod, the form factor is the only advantage, whereas the disk space is a disadvantage, yet they're the same price.

I'm not trying to dis the Slate, I'm just trying to say why that reviewer had a point.
