iPod photo. Talk about rip-off. That thing was wayy wayyyyyy over-priced, when the iPod video came out to end the short reign of the iPod photo, it was priced a lot more affordably, was a much nicer design with a better and bigger screen and included a lot more new features. I remember the price of my 20gb 4g iPod was something like $450 Australian, and the iPod photo 40gb when it came out was about $750, replaced by the $500 iPod video 30gb.
I was going to vote iPod+HP, but that was hardly a mainstream iPod. Don't think it should even be on the list really. Edit- Actually that's probably because it wasn't even sold here in Australia, might have been more of an American thing. carry on.
The Classic is a bit of a bastard child now, the neglected member of the iPod family. It's interface is just bad, way too slow.
The quintessential iPod to me will always be the iPod video 5g (in white).
My first iPod was the 4G, even though I now think it's pretty bad and probably the worst iPod Apple released (Especially the ipod photo 4.5g which I voted for), I can't help but have a soft spot for it.
Also, I really like the 3rd gen fatty nano.
