Lightroom has awesome high ISO rendering? Woo-hoo... Canon 40D must be a great camera. ;)Also for the paintery effect... It's true that Lightroom/ACR's sharpening is prone to that. But I guess that the guy overdid it with the sharpening (he said he sharpened for these tests). He needed a higher Details value, as the default of 25 is too low and often causes the photographs look a little like watercolor.
