I have owned a few idevices, a 4G 2nd Gen iPod nano, a 30G 4th Gen iPod, and a 80G 5th Gen iPod classic. I gave the nano away when I got the 4th Gen iPod, then it died and I got the classic. It had been my music and movie player until I got my recent phone and now it only is used for music in the car.
The wife has had the 3rd and 4th Gen nanos. We have both considered iPhones previously, but have never got one. If the 4s had not still been full price I may have gotten it instead of my lucid, but I am quite happy with my phone and will probably never have any other iProducts.
