I love this thing! For a funky, flat-looking speaker, it really cranks out the sound, and I'm really surprised at how good the bass sounds...the whole sound is pretty rich & deep.
I use this in my home-office and also move it to my kitchen (it's easy to move around), and it totally fills the room with sound. The sound comes out both the front & back of the speaker, which makes it perfect for where I have it.
And it doesn't hurt that I got this thing at a killer price on buy.com! If you have an iPod (and who doesn't?), you can't go wrong with this speaker.
