If you don't mind the normal bugginess of a beta, then go for it and download today. You'll immediately notice on the Retina Display that Google have fixed the issue with quality, however, this fix will only be of use to the user when it comes out as a public release. It would appear this version is made for the Retina Display as well as the other devices in the Mac range.While the Re tina Display is the highest quality screen you've ever seen on a laptop, the issue of quality is still there, whereas Apple have made their Applications ready for it, other companies are yet to catch on.This is where this beta of Google Chrome comes in.
If you own the New MacBook Pro with Retina Display, then you are in for a real surprise.
