"We"? Talking in pluralis majestatis? Or just resorting to some good old personal attack, trying to hide the lack of arguments?
The number of supporting software/websites is constantly increasing. And when you have the support, the difference to any normal display is night and day! Not to mention the flexibility in terms of various resolutions to adjust for the current situation. A non-retina display simply can't deliver there.
Not every machine is affected and if they are, Apple seems to change the screens without asking questions. Not nice, but no general failure as well. And working retina displays _are_ better, by a fair margin!
Yes really! They redesigned it (e.g. asymmetrically spaced blades, side air intakes) and even put some focus on it during the keynote. If you boast talking facts, you should get them straight before!
If you don't believe Apple and my personal experience, perhaps
Anandtech is sufficiently credible for you...
Not all pro stuff is happening in the past. Most of the missing ports can be retrofitted though and beyond that the rMBP offers some significant improvements over the cMBP you _can't_ retrofit.
Your workflow may be better suited to a cMBP, but dismissing the rMBP as Pro machine is simply arrogant. Many people seem not to share your opinion btw. - IMO it's quite telling that the cMBP is already available as refurb (and has been for a while), whereas the rMBP is not.
Ethernet and FireWire can be added via TB adapters (and then you can get even more ports than one integrated), drive is
easily replaceable (albeit not officially encouraged by Apple).
Optical media is clearly on its way out in terms of computer storage, so the constantly increasing number of people that don't need those are glad not having to pay for and drag around this ancient technology (for casual/home use an external drive is more than sufficient).
