A whole pound is "infinitely more portable"? Really? You need to go to the gym, my friend.
Seriously, the price difference is extraordinary. I guess it depends on what is most important to the user in question.
Can the new non-retina MBP be end user upgraded (hard drive and RAM)? The HD size on the non-retina is much more useful.
I have the 13" MBP from 2011.

I'm a thin, gay, twink and my small frame can't handle the extra pound.
The Retina Pro is a pound lighter, 25% thinner, and something like 38% less in volume. That's a drastic change in portability. You're just butthurt that Apple is moving into the future and doing away with upgradability. It's an amazing computer.
