MicroMemo adds 16-bit recording to iPod

There are plenty of microphone adapters for the iPod, but most can only record in the lower-fidelity frequencies available on pre-5G iPods. The XtremeMac MicroMemo takes iPod voice recording to a new level, taking advantage of the greater range available via new iPods. The unit consists of an adapter with a built-in (bur removable) flexible mic, and records 16-bit audio from 5G iPods at 22 KHz. It's powered by the iPod and will cost $79.95 when it ships later this year. Could be the perfect thing if you're ready to take your podcast on the road.
