OK, I get you guys who root for the rMBP, I really do, but those are my thoughts:
1) By Apple's own definition, the 17" MBP is the only Mac before rMBP that can be called "retina" (meaning individual pixels indistinguishable at normal working distance). I will find the link to Apple's own math if you won't believe me. Therefore, the perceivable difference in resolution should be minimal. Remember: This is by Apple's own math.
2) 17" is and has always been about screen estate. The old question "15 vs 17 MBP - What to get" is the same, regardless of resolution.
3) The weight of the 17" is not bothering me one bit. Annoying comment coming up: If the weight difference between this and the rMBP really bothers you, you might want to hit the gym. Annoying, yes, I'm serious though.
4) 17" + SSD (especially if you've got a SATA III MBP (2011)), and you will have a hard time feeling any difference between
It really comes down to this:
rMBP:
+Lighter
+Better performance (albeit very minimal in daily use)
+Thunderbolt (might be a deal breaker for some, others already have it)
+Better vents and presumably temps
+Newer tech (let's face it, a big plus)
17" MBP:
+Screen estate
+Better battery life
+No lag (next generation will solve this, undoubtedly)
+1080p can be displayed properly (big plus)
+Games will run smoother (2010-2011-models) (even with newer graphics in rMBP - That amazing res takes a LOT)
+Better speakers
+Better keyboard (more tactile - subjective)
+Easily repaired and upgraded (replacing battery in rMBP? OUCH!)
+You will save a lot of dough keeping your trusty 17" (!!) MBP
To me, this is a no-brainer. Apple always tempts me, but this time it wasn't a hard decision at all to stick with my old'n'beautiful Mac. But that's just my opinion
