    I just read a few articles claiming that Apple has been tricking us into believing the displays on some of its computers displayed millions of colours (8 bit), when in fact they were only capable of displaying colours in 6 bit.

    I then looked up dithering on Wikipedia, and found the following page:http://en.wikipedia.org/wiki/Dithering
    If you scroll down to the subheading Digital photography and image processing, you'll find that figure 3 demonstrates the effects of dithering. This effect seems to match what is happening on the screen of my iPod touch at the moment, especially when I view photographs with black areas. I believe that Apple may have used this technique on the iPod touch, to dupe us into thinking the displays are much better than they really are. Unfortunately, they don't advertise "million colours" or anything like that on their website, so I can't really take any action, but I thought this would be interesting nonetheless.

    EDIT: I just found that iPhoto, when it downgrades the photo quality to export to the iPod touch actually lowers the image to 6-bit, and applies dithering. This is probably why the photos have this dithered look about them when viewed on the iPod touch. However, has anyone noticed this effect when viewing other media, apart from photos?
