Does anyone use these with an iPod? I have the original inMotion speakers, and I see there's now an IM3 version, but I can't find any info on the altec website about the IM2, which apparently isn't specifically intended for the iPod, but rather for any MP3 player. It's a lot cheaper than the other IM versions, but I want to find out whether the sound is as good as the other IMs, and whether it'll charge the iPod as the others do. Thanks for any advice.
