I'm looking to buy an iPod-enabled clock radio. I have narrowed my choices to the following: iHome IH9B6 iHome IP9BR Sony ICFC1IPMK2BLK However, when I call the manufacturer, they all say the same thing: that they cannot be used with cases. When asked why, they told be because the radios get really really warm, and it could melt the polycarbonate case. Is it true? Also, when asked what the difference is between the iH9B6 and IP9BR, they told me the only difference is an RF shield. Would the 30 extra dollars for the IP9BR be worth it? I have an iPod Touch, not an iPhone. Of course,the difference would only matter if I can get a firm answer that cases do not pose a hazard when docked. I would want to burn the house down, now would I? Also, in that case, which one would you recommend? If they do pose a fire threat, then I'll end up the getting the DLO charger instead.
