oojacoboo, I do see where you are coming from, and it does make sense. But here is my frustration. While improvements have been made, it hasn't been enough to make me want to make an investment in a newer iPod.
This may be an overstatement and a little melodramatic, but it is almost like the days of the Centris and Quadra Macs. Too many models with not enough differences to justify the cost from one model to the next.
krusher117 asked if this was enough of an update. As someone who does not have the finances to take a loss on selling my current iPod to get a new one, the differences are not great enough for me.
With the wife wanting a mini iPod for her birthday, I don't see getting one of those and getting a 4G iPod anytime soon.
