One of the early complaints with the Retina MacBook Pro was that it had an unusual limitation on how it could be configured in Apple's built-to-order store. That's changing today, however: the Apple Store is now offering expanded configuration options for the base specification machine. Previously, the $2,199 base model only had one configuration option: a $200 upgrade to 16GB of RAM. If you wanted to upgrade the amount of flash storage or if you wanted to configure the laptop with a faster processor you needed to start with the $2,799 model.

What does this all mean for prospective buyers of Apple's high-resolution machine? Well, you can now spend just $100 to upgrade the base model from a 2.3GHz Core i7 to a 2.6GHz processor. Or, if you're afraid of having merely 256GB on your primary drive you could spend $500 or $1000 to get a total of 500GB or 756GB of flash storage, respectively. The new options don't seem to be live for everyone yet — similarly to the Thunderbolt to FireWire adapter earlier today — but they should be available to all soon.
