Hello CNet and other CNet users,
I had been shopping around for new speakers for traveling and home use and have recently been paying more attention to iPod speakers. I understand that they have been around for a number of years, but I wanted to really know the following:
What is so special about iPod docking speakers that warrant the need to make speakers designed specifically for iPods?
Are we getting some benefits from buying and using iPod docking speakers compared to hocking them up via 3.5mm audio jacks to some computer speakers?
How do iPod docking speakers compare to mini audio systems in terms of quality and functionality.
Just thought this might be something good for me and others on CNet wondering why they should dish out money for these items. Thanks.
