I actually like the fact that there is an aux port instead of an IPOD connector. #1 your not limited to the technology presented by an IPOD. #2 You have endless possiblities of connecting whatever devices you own.
There is no reason why they could not give us both the aux and the ipod connector. If I had a choice, I prefer the aux, but I would also use the ipod connector if it would have been an option.
