Since we talk a lot here about podcasts and mp3 files, it seems worth flagging this Yahoo gadget review that pits the new iPod lineup against its rivals. Here, we've got the new iPod Touch v. the Samsung Yepp YP-P2; the new Nano (with video) v. the Sansa View, and the iPod Classic v. Microsoft's Zune. The net result is that the new iPods come out ahead, but not by much. Get review here.
(For another review of the new iPod Touch, have a look at this piece on Gizmodo.)
Quick note: As part of the new lineup, the iPod Classic features a new 160 GB model for $349. It apparently holds 40,000 songs (twice as many as the previous model), which translates to three continuous months of listening entertainment. Imagine how many mind-expanding podcasts that could include.
