Boston Acoustics + iPhone = Duo-i Plus
Besides the iPhone compatibility, the Duo-i Plus's upgrades are completely aesthetic. It's available in glossy black or white, a bit shinier than the Duo-i. Besides those two changes, it's basically the same iPod dock as its predecessor. It pumps out music through its dual 3.5-inch drivers, and incorporates dual auxiliary inputs, dual sleep/wake alarms, and an AM/FM radio tuner.
If iPhone compatibility and a glossy finish are worth an extra $50 to you, the Duo-i Plus will retail for $249 when it ships in October.
