Not as useful as reviews claim

This company(Olympus) cheats customers by luring them to believe that VN4100 is the same as VN4100PC.The difference lies in the computer connectivity.This Voice recorder which bears the VN4100 does not have USB Port and thus CANNOT do a file transfer to the computer.So the question of email sending of voice files is impossible.
Also, the battery functionality is not good.The moment the hold button is on and the battery is replaced the machine crashes and becomes useless.
The design is sleek but it has not substance.

Satisfied, but be careful when you change batteries

The VN4100 is an excellent handheld digital audio recorder. I'm very satisfied. HOWEVER, when you change out the batteries, be sure the HOLD switch on the left side of the unit is in the HOLD position. I changed out batteries with the HOLD switch in the ON position, and it killed the unit. Still, it suits my needs, so I got another. Just be careful changing batteries.

Worked Great, Died in 5 Months

I liked this product while it lasted. I used it as a backup to take notes in conferences and training sessions. I am a technical writer and it was an invaluable aid in cross-checking spoken information.

However, it conked out in only 5 months. For no good reason as I treated it decently. It lived in a special pocket in my handbag with my mobile phone and was never dropped or anything. I changed the battery and found that the unit was no longer responding to any button and could not be accessed, even though the battery was full and correctly entered. All I have is a message saying ERR on the screen and many hours of precious information LOST.

So my appreciation is mitigated. A good product but 5 months is too short a life.
