It also hasn't been mentioned yet that they have killed the option for a non-glossy / matte screen, which I can imagine a lot of pros being very upset about, since it's still offered on the regular pro's for a premium (used to be the standard)
In regard to resolution, when I bought my Macbook Pro (15", 2009, Core i7) I opted for the Higher Resolution Anti-Glare screen, and boy am I glad I did, the extra resolution is definitely welcome, it means I can have an internet page and word document open at the same time, work in final cut with greater ease, and also work with photos in photoshop easier. The Retina display will be much better again! I was worried about the writing / screens being way too small to be readable, but it was never an issue

Also, I'm now in a similar situation as I was when I ordered my last laptop... I need to upgrade, and I've been wanting to upgrade to desktop (iMac) however they haven't upgraded them (similar situation last time) and as such, the Laptops have actually surpassed / matched the desktops in specs.. so it makes the decision a lot harder.
