Apple are trying to stop people using 4 letter words ending with ‘pod’ in the US, and the practice seems to have extended to Australia where Apple are suing local developers of the mPod, LPod, BPod, ePod and DigiPod.
Fortunately it seems that Line 6 have trademarked pod in Australia.
Otherwise I guess it’s time to refer to them as xP*d’s or something along those lines.
