> I was reading around about the new Macbook Pro retina display today and there were quite a lot of comments about how apps may need updating to support it. Chrome was mentioned as an app which doesn't look good currently, I saw the pictures, it's not nice. I understand apps needing 2x artwork piece, that makes sense. However I'm unsure how a normal app (like Chrome) needs special treatment
Because Chrome is not a "Normal" app, and it does not just use standard API for rendering. Usually everything just works. You can already test that on your standard screen by enabling HiDPI using the Quartz Debug utility that used to be part of Xcode but is now distributed in an extra package (the Graphic Tools package IIRC).
It may not reveal subtle rendering bug, but will let you know if something goes really wrong in your drawing code, and coordinate computation.

(inserts a bit of doubt there, antialiased is never as good)
