I am about to buy second wall charger and Palm's MicroUSB Power/Audio splitter/adaptor for office use. Before doing that, I was wondering if somebody has come across a Desktop cradle+charger which has builtin MicroUSB Power/Audio splitter i.e. a desktop charger which has MicroUSB Audip port as well.

Yeah, I know I can use bluetooth audio headset but above solution works best for me.
