It's not like we haven't seen miDocks before
, but Polk Audio is enjoying the spotlight at CES and releasing a trio of newcomers to mingle with your iPod. Up first is the miDock Studio (pictured after the jump), which takes a subtle hint from the late iPod Hi-Fi in the design department and features a pair of 3.25-inch drivers and the ability to operate on AC power or from eight C-cell batteries. The miDock 10 (shown above), on the other hand, is entirely more suited for being hoisted over your left shoulder when pouncing down the street, while the diminutive Portfolio can be folded up for easy transport and operated on four AA cells for over eight hours. Notably, the Studio and 10 also sport USB inputs for direct computer connections, and the trio will run you $229.95, $179.99 and $119.95 in order of mention.
