don't know it, but, like anything in digital recording, you will get good results eventually if you stick with it and spend time properly experimenting with mic placement.

I presume it has a built-in mic but...

1. can an external mic to be connected? if not, well, it might be considered quite a limited tool. If so, what are they? (1/4 inch jack, XLR etc etc)

2. do you actually require a portable recording device? do you already have a decent soundcard on your computer? do you own a laptop?

3. what software will you be using to edit the recordings you make with it?
