Those of you who own or have used both the 5G and 6G iPod Nano. What are you thoughts? Which one wins out in your opinion? I personally am teetering on picking up a 5G Nano while they are still available as I feel the new Nano is simply a iPod Shuffle Pro. The new Nano, IMO, has had most of its great features (video recording/playback, voice recording, etc) removed so I cannot justify the purchase. This is, of course, just my opinion so I would like to hear from you all. Thanks.
