on 2.4 dev, and 2.3.x I was encountering intermittent crashes to desktop.
Also I was not able to view the textures of the world, and it was pretty much just a night view for me, forever.
I am encountering far fewer crashes since the update, and I have night / day as well as actual countries and land masses appearing on my globe.
So a big thanks to the team.
I'm on a MBP 15" 2.4 Ghz Core I7 running Lion (the most recent edition)
