I looked at the tech. specs over at apple.com, and they claim only 17 minutes of skip protection, as opposed to 25 on all other iPods. Doesn't this mean that the hard drive will have to be accessed more often, causing a greater battery drain? Why would Apple do this? I'm starting to rethink my plans of getting a 60gb...

Im sure there is a good reason to it.
Also, why would they make a 15 hour battery that would just get drained faster?
There's 32MB RAM for both, but the Photo's software/OS is probably a bit larger, so there's less room for buffering songs. The hard drive will spin up more often, but the battery life is still longer according to the specs which are probably reasonable estimates.

I noticed a bunch of people posting that their iPod photos were locking up when they jogged...
Well, I just noticed when I was on Apple's website checkin out the specs, the 4G has "up to 25 minutes" skip protection, when the photo only has "up to 17 minutes".
I don't know if this has been pointed out yet, but I am VERY suprised to find this out. While I don't jog, I still think there's a big difference.. and I may still notice it when using mine, maybe if I'm walking briskly or something...
I'm wondering WHY there is a difference! Maybe that's how they manage to squeeze "up to 15 hours" of battery life...

ah, once again i see im late to the table.. oh well..
[zerophase] skip protection is when the ipod hdd reads ahead, in the ipod photo's case, up to 17 minutes of audio, and then plays from stored memory, as opposed to running from the hdd constantly.. so with the stored audio, if you shake your ipod about it's not going to skip because it's playing from the ram instead... it's just like old school portable cd players that had skip protection.. since those worked with lasers, it was very easy for them to skip, so it was constantly store the next 20, 30, 40 seconds of music, so that if the player did receive a jolt, it would keep playing while the laser finds it's place...
