Unless you've been sucked into the iBubble, you'll probably know by now that Cowon makes some pretty terrific PMPs, like the S9. Its latest model, the V5 HD, has just been outed and promises 720p viewing on its 4.8-inch screen.
People waiting for the widescreen touch iPod may have something new from Oppo to tide them over. Their V5 is only 11mm (0.43 inches) thick and actually comes in a 16:9 ratio (unlike the iPhone). That's true widescreen on that 3-inch screen, if you're counting.
