Have you made your choice yet? I haven't manage to see a rMBP yet (an errant two-year old and DIY precluded a trip to an Apple Store), but I've ordered a 2.6GHz cMBP with anti-glare HiRes.
The pros and cons of the new rMBP were - for me - so closely matched that I would almost certainly have been happy with either machine. In the end it came down to the true anti-glare and - to a lesser extent - the expandibility of the cMBP. The fact that I already have a good SSD means I won't miss out on the SSD speediness of the rMBP, whilst the possibility of running two SSDs in RAID 0 and potentially upgrading to 32GB is an added bonus.
Realistically, I don't think you can go wrong with either of these MBPs. Good luck with making your decision.
That's awesome. I think you made the right decision. There is definitely no one right answer for anyone here. I keep trying to reiterate: you have to look at how you will use it, your specific needs, and then make a decision. There is no magic answer. The pros and cons of both models are stark. The fact that you already have an SSD is a big factor in my eyes.
I'm still trying to make up my mind. The cMBP is really attractive to me for all the reasons aforementioned except one--screen real estate! I utilize a program daily that requires a ton of screen real estate, so it's a very important concern for me. 1920x1200 is so appealing! I definitely want to see it in person though, or at least see some screenshots so I can decide for myself if it's usable. I am really concerned about being an early adopter of this model. I think I can deal with some blurry web imagery. I'm a bit confused why Apple couldn't use a different pixel scaling algorithm (there was another thread on this somewhere in here--I forget the title) to prevent the blurriness, but whatever--I can deal. I'm sure there will be a couple months worth of issues until they iron out the kinks. The Apple store lag and the Safari scrolling bug makes me feel like this release was rushed.
Actually my perfect solution is to find a late 2011 model at this time, and try to get a Retina model in a few years when the world is more prepared for HiDPI displays. Unfortunately I've been having trouble finding one for the right price (understandable, they just bought, why would they be selling unless they are really desperate for a '12 model). Kind of like we talked about before--I want to be extra, extra sure that there is no issue with the GPU pushing around all those pixels of the rMBP, so I'm waiting for a few more reviews to surface, but honestly, I don't think it's real issue. I think we just got scared by all those initial reports. So if I can't find a 2011, I'm still leaning towards the bottom-spec rMBP w/ 16GB ram. I wish they had dropped the price of the classic a bit more, but I guess one can't complain. They really should have made 1680x1050 standard, but...it's Apple.
If I get the rMBP, I'll definitely be jealous of all that extra space in the cMBP. Honestly, I could care less about the new slim form factor. The cMBP is plenty slim enough for me. I just feel like I'm getting more for my money with the rMBP--it's really, really close though, hence the tough decision.
