An Open Letter To Digital SLR Manufacturers
Michael Reichmann, editor of Luminous Landscape, has published an open letter addressed to all DSLR manufacturers, calling for the addition of full-feature exposure histograms to all future DSLR models.
“In recent years I have been especially interested in digital SLRs, because these clearly represent the future of mainstream professional and advanced amateur photography.
Recently I have noticed a disturbing trend though — as several companies bring their first DSLRs to market — and it concerns histograms. Or, I should say, either the lack of or poor quality of histograms.”

I like his points about histograms, but it's nearly impossible to fit all of them into a small LCD. I also kinda liked the idea of blinking overexposed parts, but after thinking for a while i understood that on any well-exposed picture there will be highlights, and they will count as overexposed parts (since they will have brightness 255). Thus, we need to count the area of over-exposed parts, and only flash the ones that have large area.

The Generic Blanket 'criticism' in Mike's letter should have been more precisely targeted to those manufacturers that are 'guilty', (Olympus: E-1), etc., IMHO.

The EOS 10D flashes the parts of an image that are overexposed, which is quite useful. It also allows you to see the image and histogram at the same time, with the image on the left and histogram on the right. It doesn't display the RGB channels though, just combined.
