The camera records in color, 352 x 288 pixels, at 15 frames/second. It does record sound, albeit not as crisply as one might like. Running the sound through an EQ would help enhance the vocal range, and suppress the noise from air conditioning, ambient background noise, etc. The audio quality is not much different than any other omnidirectional mic of its size. One interesting thing - the opening for the mic is underneath the clip, so it is completely out of view. The only issue I have so far is the tiny LED that lights up when the camera is recording. It could be noticed by someone paying close attention, or if you were wearing a white shirt and have the pen/cam clipped in your pocket. The faint blue glow could possibly be seen, but in an outdoors location, unlikely to be noticed.

One last note - the device, itself, is a bit larger than a standard pen, but not outrageously so (150mm x 15mm x 15mm). It may look a bit odd in a shirt pocket, but since only the top 3/4 inch or so is visible above the clip, most folks won't think twice about it, and certainly not suspect that it is a video camera. Placement of the mic under the top of the clip will keep it from being muffled by a shirt pocket, too. Nice design.
