As the core audio system in the previously-covered iMini Pet, iMini Cute ($50) is a cube-shaped, simple clock radio made almost entirely from plastic and shipped in multiple versions, differing in the colors of their metallic side panels; all have white actual metal speaker grilles on their sides, an iPod dock on top, and a backlit clock on the front.
There’s a battery compartment in the back in case you don’t want to run it off the included wall power adapter.
By comparison, iMini Rainbow ($50) is solely wall-powered, removing the battery compartment and adding a translucent plastic layer to the bottom with a glowing, multicolored lighting system similar to iHome’s iH15; it also pulls the metal speaker grilles in favor of a more plasticy side appearance.
