i'm researching some ipod stuff before buying so any opinions and experiences would be greatly appreciated. i'm buying the mrs a pink mini( really, it's for her...) and i want to get a larger ipod to archive what has become a large and messy collection of cd's. i was going to buy the 4g 20 gig but it doesn't come with a dock which i'd like so i can use the line out to my stereo system. i noticed the 4g 40 gig comes with a dock and is only $50 more...which means there is basically a $10.00 difference for double the storage space when you factor in the price of the dock. i know the 40 gig has been EOL'd but does anyone see any reason not to buy it? we don't need a photo ipod or color screen..those options just aren't important to us. just looking for some opinions before i place my order. thanks.
