Dave Winer thinks the iPods interface is too hard:
It's impossible to use while driving, in fact it's impossible to use while walking. If I want to play something else it's a multi-step error-prone process. There has to be a better way.
I've not had this issue, but I'm also almost half his age... but on the other hand, my mom has no issues either. So I wonder if this is an actual issue with the interface or someone that wants to create a Podcast listening device creating some FUD about his competition?
