GoPro Hero2

I can't believe the Hero 2 rattles just like the original hero. 
I've asked for a replacement from Amazon in the hopes that the one I received is actually bad and that the hero 2's aren't supposed to be like this. 
I used GoPro Hero2 recently. This does not seem to produce even 8 Megapixel shots at the appropriate settings (not mentioning 11 Megapixels)! Pixel noise is huge and color representation is poor. The color representation seems gray, flat, and dull... It is rather 20$ worth of production value, not a pro or semi-pro as advertised. A lot of plastic parts that ship with the camera are merely discarded and never used again. Does it seem wasteful? The rigging does not allow to tilt the camera up, while on harness. Perhaps there are other rigging parts, which need to be purchased the moment camera arrives.
The results are not professional, as advertised. A 100$ camera I used previously for the last 4 years takes better pictures. Looks like if GoPro used different processors to shoot their beautiful commercials! Or did they do substantial corrections during editing of their broadcast videos we all fall in love with? 
When the sensor on GoPro Hero2 gets warm (during battery charging), camera start to produce stripes and other artifacts, which don't go away if the camera is turned off and on again. This is the image on Flickr from my experience. There are other images there too, showing my attempts to get the best out of this camera.
