Comet PANSTARRS does not appear to be an impressive naked-eye object...in fact it is quite difficult to find.  You need to know where to look.  But it is possible to pick it up somewhat more clearly with some timed exposures with a digital camera.  Here is what I managed last night in spite of high clouds:

15 second exposure at F22 ISO 320 with Panasonic GH2 75mm (150mm effective)

5 second exposure at F13 ISO 320 65mm (130mm effective)  cropped:

A shorter exposure with a larger f-stop picks up more of the head.  Longer exposure with smaller F-stop shows more of the tail.  Hopefully more to come in the next few days.
