Summary: I originally bought the Cyber Acoustics Portable Dock for iPod ($47) for use in my home gym. But after discovering that the CA didn't support my iPod 3G, a 30 GB model purchased in 2003, I returned it to Amazon and began searching for a suitable replacement in the same price range.
Summary: Hands down. I recommend this to every one of my friends. I love it so much that when I lost my first one, I ordered another one the next day. The fact that you can plug it in or pop in some batteries and carry it around is great.
Summary: I used to plug in my iPod to the stereo speakers in our family room with a $9 splitter cable. But earlier this year, my husband upgraded his Tivo & moved the old one into the family room & there were no more jacks for me to use for the iPod. (BOO! OTOH, it's nice having two Tivos, now, too!
Summary: I bought this a year ago to go with my 60gb classic. Incredible sound even if it is a little bass-heavy. I just upgraded to a Touch 2G and I was very happy with how it fit in the IM9 without any dock adapter. The problem is that it won't charge the Touch!
Summary: Had this ipod speaker for a year and the sound quality meets my high standards for my bedroom since my living room stereo is a $2000 system. I was delighted by the deep bass coming from a small portable system and I am convinced that most people will enjoy listening to it.
Summary: I purchased the Altec Lansing inMotion iM9 for my wife for Christmas to use with her U2 ipod. It works great. Nice sound, plenty of volume for her purposes. There are not many functions (no E.Q., remote, etc.), but it is easy to use and the included backpack was a hit and makes portability a snap.
