The main criteria for iPhone / iPod speaker dock systems seem to be: 1) Charges the IPOD TOUCH 4G; and 2) Has excellent sound. This unit does both. What else do you need to know?
Very pleased with the Logic 3 i-station. Perfect little travel item which comes with a handy carry case. The bass is not pounding but for its size it still packs some punch. Remote control is also very handy. Nice price too!
