My iPod spends more time in its speaker dock than it does anyplace else. The dock resides in the kitchen; the iPod serves up tunes when the Cheapskate clan is cooking, cleaning, eating, and so on. My only regret is that it doesn't have a radio, meaning we can't listen to NPR when the mood strikes.
That's why I'm seriously eyeballing the Logitech AudioStation, an iPod speaker dock that also has an AM/FM tuner. It's packed with other features, too, like a remote, an audio input jack (for connecting non-iPod players), and composite and S-Video outputs (for watching iPod videos on a TV). It also charges your iPod, of course, and cranks out 80 watts' worth of audio goodness.
The AudioStation sold for $300 (!) when CNET first reviewed it (and rated it 8/10), but now you can grab one for a mere $49.99 after a $50 mail-in rebate.
Note that TigerDirect won't let you return the item unless it's defective, and even then you can only exchange it for a replacement. On the plus side, it's backed by a 24-month Logitech warranty.
