brsboarder said:is there a hack to make this work with any of the other ipods, or is it going to be proprietary. I would like it to work on my 3g and don't really need a new ipod, nor would get a nano at this point.
No, it won't now and won't ever work with Hard Drive based iPods.
It would cost Apple far too much in running-related repairs to the HDD, the reason they chose the nano is because of the flash memory that hasno moving parts.
