One of my comments was along the lines of:

I've fallen in love with the form factor, but if I hadn't have tried it out for a couple of weeks I wouldn't have thought it was so important. You're going to have pull off an impressive marketing feat to convince the average punter that it's a big deal, and worth the money.

And I think that still stands. For instance I'm seeing iPod marketing on trams, and the das are focussing on capacity. If that's all the public sees then it's going to influenced into thinking that capacity is the key feature.
