May not be that related but thought I would throw it out there:
I just purchased an Otterbox Defender case for my Ipod touch 4G but it does not fit onto the docking station with the case on. It is a pain to take on and off each time I use it. I plan on using the docking station quite often for in home entertainment/ambiance music with my touch.

Does anyone know of a decent case that does not interfere with docking stations? Do I really need to get an adapter?

Thanks
