It only got slightly thinner and slightly lighter.
But still, that battery life. Dang, and like you said Matto, $200 dollars cheaper.
It's a shame Apple isn't doing the same thing for their iPhone/iPad lines as they are for their Mac lines. When it comes to Macs, I am that Apple fan that feels they need to upgrade each year. Alas, I will resist, but dang, wish I waited.

Only the 13 inch saw a minor design change.
Gotcha. That was hella confusing there.
