The issue with the iPod and mini is battery power, they did an alright job with the 4G however that is not a great improvement, Come on Apple they seem to be falling back on battery power on they mp3 players, and top of that you want to add more into or attact onto the iPod and mini, lets see battery power fall back to the previous versions.
The #1 request for iPod and mini is battery, Apple is not getting they act together on this. I don't need all the fancy WiFi, ird remote, Blue Tooth, yada yada yada......If it is going to cut on battery power toss it out.
Soemthing tells me that the iPod OS along with HW management is not working to effective performance thus the battery won't even last on a single full charge for 18 hours.
Great if we need to keep teh iPod and mini plugged it makes it a portable need to be plugged into the power socket music libary player.
Beats the purpose.
