I don't agree. It simply means that in order to make the newly announced MBP look better they had to compare it to their first notebook.
I don't think it is a sign of them doing anything different. This past week was the 15th anniversary of the iPod and Apple was completely silent.
Cool you don't have to agree and pretty much the iPod is "Dead man walking" at this point so no reason for them to mention it. It was the 25th anniversary of their first portable which they did acknowledge that was different.
