I have had exactly the same experience. Plus, there are some awesome deals on the MBA. Also, I would suggest that folks go to the Apple store and put the MBA and rMBP side by side to check the difference. I am sure it can be noticed, but it is really not that big of a difference for most people. If you bring along someone that doesn't know there is suppose to be a difference, and ask them to describe which screen is better and why....my guess is most neophytes wouldn't be able to do it.
"Retina" display is an Apple marketing term, and once indoctrinated into the hype, it's easy to believe you can't live without it...but you can. So, when folks say the MBA screen is unusable, I just have to laugh. I use one everyday for work and home. My daughter is a college student and my son is a HS student, and they use their MBAs all of the time for school work. If you go to a college campus, you will see tons of students using the MBA. Walk into a Starbucks....half the laptops are MBAs. Why? Thin profile, light weight, terrific trackpad, OS X, Built-in Apps, 12 hour battery life, and affordable pricing.
If someone values a retina display and other features of the rMBP, then by all means buy the rMBP. It is going to be about 30% more than the MBA base model. That's fine, and it might be the best choice for you. After buying, just don't go onto tech forums and post nonsense about the MBA display to justify the decision.
