no. they advertised the 17" as 46% brighter. they have not said anything about the 15". one guy here on the boards said he called apple and they told him the 15" is 26% brighter but i call BS. i think the rep pulled a number out of his ass. and from the reports i am reading, the 15" does not appear to be brighter than the last 15". sorry folks but the 17" display is getting the awards for this revision. glad i went with the 17".
