It’s not a particularly well-known name (though it is a particularly dumb one, which might be part of the problem), but PoGo! Products has a couple of ultrathin and ultralight MP3 players coming out that have some cool extra features that not even the mighty iPod has. The one ounce, 0.37-inch thick RipFlash Trio has 128MB of memory, a built-in FM tuner, a digital voice recorder, and the ability to directly record from any audio source as MP3s. The RipFlash Pro has the same amount of memory as the Trio, but lacks the FM tuner, which apparently had to go to make the Pro just three-tenths of an inch thick.
