If you want to have a slick little speaker for your iPod and torture a fish at the same time, the iPond was designed with you in mind. While it's certainly a unique little product and is pretty cool looking, it's apparently much too small for fish to live in and will probably end up killing any fish you put inside it.
OK, so maybe that's not the best thing in the world. But it's pretty cool looking, so what are you to do? Well, I'd just leave the fish out of the equation and put something else in the water. You know, like a scuba man with a treasure chest like you'd put in a regular sized fish tank. But then, that probably wouldn't make it worth the $70 price tag. Oh well, it's not like there aren't loads of options for iPod speakers anyways.
