CNET Asia have posted their preview of the iriver X20 (4GB) media player which is expected to be available some time in February. 'Controls are simple. There is a hold switch, a back and power button. A five-way control center dominates the proceedings and, like the iPod, the X20 has a scroll wheel for content surfing. But in iriver's case, it's mechanical. The scroll wheel, or more accurately, the scroll ring, is a bit on the slim side and tries to compensate with grooves to get a bit of grip going. It still feels flimsy, though, and we are not fans of it.'
