No surprise with the pricing
Not really surprised with the pricing.
Most of the cost increase with the 2.6 is the SSD drive. $100 2.6 over the 2.3 makes sense. It's only about a 10% boost, which is basically unnoticeable in use. 2.6 v 2.3 was basically of no interest to me, even for $100.
From the beginning I thought a 2.3 with a 512GB ssd would have been a solid choice. I'd like it a lot better if the SSD wasn't a $500 upgrade though. $400 would be a lot better. At $500, they are basically charging $900 for 512GB storage. You'd think there would be some allowance for the fact you are starting with a 256GB card.
It's a tough sell to say that 1/3 of the price of a rMBP is from storage.
I'd much rather have a 128GB SSD for a boot drive paired with an internal 500MB HDD. I'd get 90% of the performance of an all SSD solution for a fraction of the price, probably around $300.
