I disagree with you that the retina MBP makes more financial sense. It looks like you bought a near-maxed out standard MBP and then upgraded it with expensive components on top of that. The power of the standard MBP is that you can buy it with minimum specifications and then upgrade it later, either when you see a good sale, prices have dropped, or worst-case scenario, when you absolutely need it. Case in point, I bought my MBP with the minimum specifications available (4 GB 1300 MHz RAM, 500 GB 5400 RPM hard drive). RAM upgrade to 16 GB and a faster clock rate (1600 MHz) for just under $70 USD (it's even cheaper now), and I'm close to upgrading the hard drive to a 500 GB SSD for $270 USD (and if I keep on waiting, that price will continue to drop - some sales have taken it very close to the $250 price range). That's well under $400 for those upgrades, which would have cost me much more if it had come from Apple. But the benefits don't end there, as I'd have the option of going to 32 GB of RAM (if it ever comes out in DDR3 and if I really need it), and I'd still be able to upgrade the SSD later on.
I never understood the "if you can't afford this, you probably shouldn't buy this anyway" argument. $200 isn't a deal-breaker for me, but if I can get the same thing for $100 or even less, why the heck would I want to part with $200? The retina screen is really nice and I look forward to having a computer with one some day, but to max out a rMBP costs an awful lot - and those costs aren't associated with the screen, but with Apple's decision to solder everything to the board. Partly out of principle and partly because the retina isn't worth that much to me, I haven't bought a retina MBP. Valuing upgradeability and not blowing money to max out a system because you can't do it yourself for cheaper is a big theme of this thread. rMBP owners and potential buyers shouldn't feel spurned by it.
