PC Magazine have published a review of the Helio Fin/Samsung SPH-M513 music phone. 'Dull gray, measuring 4.1 by 2.1 by 0.5 inches (HWD), and weighing 3.35 ounces, the Fin looks a lot like AT&T's Samsung A717—and like nearly every other slim flip phone out there, for that matter. When the phone's closed, there's a tiny screen below the flashless camera to show battery remaining, signal strength, and caller-ID information. Flip the phone open for a large 2.3-inch, 320-by-240 screen that's easily readable, and a disappointing keypad. The Fin's keypad is entirely flat—there are no physical cues whatsoever around most of the keys, not even the slight bumps or ridges you find on most flat keypads (except next to the 5). As a result, texting is particularly difficult to do.'
