You wanting to buy an iPod, or already have one? How are you going to get images from a CF card to the iPod?
If you are looking for storage capacity, i'd suggest a microdrive, it might end up being cheaper than the iPod.
Xdrive Pro looks good, but damn bulky if you're going to use for MP3. Don't know how long the battery can last, although you can make it last longer (AND BIGGER) with the ext battery pack. I found that the Nixvue DA2 transferred files from the CF card much faster than the Xdrive Pro. I also found that the Xdrive Pro's GUI speaks less plain, simple English than the Nixvue DA2. Nixvue DA2 is a better buy IMO.
yes, i second this. although the ipod is fantastic for music and its other additional capabilities, it's primary function is NOT to store photos. not sure about nixvue, but me and fred carry our ibook around to d/l our files. for emergency purposes only then will we resort to use of the ipod for photo storage.
