Also in those sunny situations, there's plenty of light to be shooting at ISO200 or even ISO100, so noise isn't a huge issue anyhow. Though you're right, if you were after the best camera possible noise-wise, white would be the better choice. But like temperature distorting the optics of lenses, the effect isn't the big night-and-day difference that would cause all the manufacturers to make the switch, especially over simple tradition, branding, and users' aesthetic preferences.

The camera shop told me that Canon L series lenses went white to reduce heat - so why is everyone else so keen on black? Anyway - the K-x seems great, though it's early days yet for me.
