My immediate reaction: My score is now forever unrelatable to all except those who took the exam between 2005 and 2014. Not that anyone has asked my SAT score since I got into undergrad, but now a sizable group of people who did substantially poorer than me will seem as though they did extremely well (a 1550, for example, means something very different depending on which exam you took, while my score of above 1600 will immediate remind people I took the 2400 exam).
It doesn't affect me at all, and I'm not complaining, but that's what ran through my head.
