iPod speakers are a dime a dozen. There are big ones and small ones; black ones and red ones; some with alarm clocks, and many with built-in docks. As one might expect, you don't have to look hard to find models with integrated FM--and even AM--radios, but if you must have cutting-edge tech, HD radio with iTunes Tagging is where it's at. Among the handful of models offering this feature is the JBL On Time 400iHD, a tabletop speaker dock with JBL's signature space-age design. At $300, the On Time is anything but cheap, but the plethora of features and excellent FM radio reception may make it worth it for some. .
