Summary: I bought two Units for my Daughters in College. Before the purchase I called Olympus to make sure they were fully compatible with Vista and was assured they were. When I loaded the software on the Vista Laptop I kept getting 3 or 4 error messages before the program would load. I reinstalled several times trying to fix it. Nothing worked. I called Olympus again and was told to just close out the error messages each time and the program would work.
Excerpt: I love this recorder, but mine almost immediately displayed a defect. The sound wavers, like a tape recorder whose capstans are dirty or oily. I can't imagine why a fully digital device would exhibit analog behavior, but it does. The problem doesn't seem to stem from the recorder's position or movement as the recording is made. Wavery recordings can still be deciphered, but they're a pain. I'm seeking a replacement unit.
Summary: I compared this recorder to the Sony ICD-SX25, and I like the olympus hardware better only because (1) the backlight display comes in handy more often than you might think; and (2) double the memory as the Sony. But, I went with the Sony and returned the Olympus because the Sony software is a million times better.
