13.0.3. Unfortunately, it doesn't snap the cursors under screenshot. Just choose any brush, enlarge it, or go to the gradient tool. The "+" is very pixelated, as well as the gradient examples in the "Editor" panel.
For the brushes, I've noticed that if I zoom in to the canvas, then the cursor also zooms in respectively. When drawing, it does give a fairly accurate representation of what I should expect to see.
It's not like I'm dealing with vector graphics in Photoshop, so I think the behavior of the brush is intentional.
As for the plus sign (crosshair), I don't think it's pixelated. I think they've done their best to make sure it's visible. If they made it any sharper than what it is, it'd be impossible to see.
The gradient samples in the editor are indeed pixelated, but do you really need to nitpick those? I had to put my eyes literally within 2 inches in front of the screen to see that it's pixelated.
No, iTunes 11 artwork in the dropdown is still very much pixel-y, refer to here.
Anywhere else? Because it's just that small part that I'm seeing the pixelation, and it's not everywhere.
And honestly, if you'd just set the resolution to either 1680 x 1050 scaled or 1920 x 1200 scaled, then you wouldn't notice any of that. If you have such good eyesight that you can see pixelation from pixel doubling, then you should be able to work at 1920 x 1200 just fine.
