TUAW reader Jeff wrote in with this little tidbit: "I haven't seen any mention of the addition of the feature on the 5g ipod that puts the little blue dots next to the podcasts you have yet to listen to just like itunes does. On my 4g it just listed the podcasts like any other tune."
Gad zooks! I didn't notice this change on either my iPod nano (which does the same thing; thanks for verifying, Laurie!) or on the new iPod, simply because it made such sense that I thought the feature had been there on the 4G. Coolness.
Good catch, Jeff. Thanks!
