Still has the cutout, thank goodness. But still sometimes is a bit of a challenge for those with less dexterity to open. I use my fingernail in that cutout.
That's the entire point of the cutout, actually. I'm sure Apple would love to save the step of machining it, but they DO realize it's a required part of the case to make it easier to open.
So no, the cutout's not going anywhere, short of Jony Ive being supreme dictator of the world. (The only alternative would be a button or a slider to unlock, but that has all sorts of design issues).
Anyhow, the biggest problem I see is the keyboard. The MacBook's keyboard already takes a little getting used to, and I know a bunch of people who hate it, but I have to admit for such a low-travel keyboard, it feels pretty good. I've had low-travel keyboards on laptops before and most are genuinely awful - bottoming out way too early, but the MacBook's one feels pretty good - it doesn't feel like I'm bottoming out at all.
