The VN-4100pc was given to our not-for-profit. We will find use for it, but it has serious problems.We had hoped to use it for recording oral history interviews by loaning it out to members, some of whom are not technically orientated.1. It will not work with our 64bit Vista computer. The Olympus site says it is not compatible with that OS.2. The software must be installed on every computer that it connects to (i.e. no drag and drop transfer.)3. Its best mode is 4bit/22kHz for a bit rate of 88kbps. (As a comparison, the little $30 Sansa Clip MP3 records voice at 16bit/24kHz or 384 kbps but does not have as good a microphone.)4. We have no Macs, but some of our members might. Its not compatible with Macs.Its internal microphone seems good. Its controls are a big improvement over our older Olympus DS-2.If you intend to use it on more than one computer, this is not a good choice.
