Oh, I would love it alright, I usually swim for a good hour; sometimes more, sometimes less. And I'm one of those people that really gets a better workout when I can do it to some good tunes. Not to mention swimming laps is boring! Several years ago I tried a "waterproof" radio that clipped onto your goggle strap, but I couldn't get reception on the thing once I was in the pool. I am not questioning whether the player would be a good gadget for me, but rather the quality of this particular item.
From the pics on the website, it looks like it could be a little bulky. Also they mention it comes with a rechargable battery, and sometimes those just dont seem to last. I am curious if anyone out there has actually used this thing. It seems like it's pretty new on the market - maybe I should give it time and see how the reviews come out.
