3G 15GB iPod.
Note that the above review is of the 'first series' of the 3G (3rd Generation) iPods, for they now have the updated software and come packed with iTunes. The reason for selling is that whilst it's a damned great portable jukebox, I'm looking for something that will support a bit more of active lifestyle in terms of accessories, so I'm getting an iPod mini. The 3G 15GB isn't even that big, it's just that finding accessories like armbands that don't make you look dorky is a task in itself. Fits great into your pocket, though
Otherwise, it comes boxed with the original manuals and the latest firmware revision, as well as the latest version of iTunes (4.7) on CD, so you can ignore the older version that came on the install CD.
Only a few minor scratches and such, simply from daily use. Planning to polish most of them out with Brasso, anyway, so it should look near-new.
Like in the topic title, $299 + postage.
