This is great news for everyone except early adopters. Instead of being locked into Apple's pre-configured options for the MacBook Pro with retina display, you can now freely configure your machine in any way you want. You can mix and match processor, memory and storage options to fit budget and performance needs.
For example, you can select top speed in the processor without having to pay extra for storage, keeping the cost down at $2880. Or you can keep the processor speed low and add more storage for $3100, which is what I wanted to do with mine. [Apple via Twitter]
