We're talking about rMBP 13 vs MBA
Let me get this straight. You are comparing the i7 in the macbook air to the 15 in the macbook pro. Are you kidding???? I compared i5 to i5 and i7 to i7. This has to be the most ridiculous post I have seen.
Obviously I'm not comparing a quad-core rMBP 15 to an MBA. The OP and I are comparing the MBA to the rMBP 13!
You just proved the most powerful macbook air processor, the i7, is STILL less powerful than the entry level macbook pro 13" processor. You made my point completely. That doesn't even take into consideration the rest of the 13" line and the 15" quad core line. That's like saying the imac is basically a mac pro with a screen because of the highest model imac scores matching up, even a little higher, than the base mac pro.
Take it easy, Dude. The comparison is that the better MBA option (the i7) is COMPARABLE to the better 2.8GHz rMBP 13 (excluding the rMBP i7 CTO option). I would say that <10% CPU difference is comparable. Many people wouldn't even notice this except for long-running tasks.
You said "A macbook pro is basically he same as a mba just with a retina screen". This is ridiculous . This comment insinuates the air line is basically the same as the pro line which is laughable. It does not mean the most powerful air i7 is only moderately less powerful than the lowest pro 15. That would negate the whole less powerful air line and the more powerful pro line.
The OP stated this, and there are obviously differences in product positioning. My point is that the PERFORMANCE of the MBA (i7) and rMBP 13 (mid and high-level, not CTO) are quite similar. Others have mentioned that although the MBA screen is of lesser quality, the retina screen in the rMBP 13 can appear laggy. I'll accept that the rMBP has Iris 5100 graphics vs HD5000 in the MBA, which no doubt helps the retina screen.
Amazing. Not in any world, fantasy or otherwise is this accurate "A macbook pro is basically he same as a mba just with a retina screen" just because one model out of each lineup is close.
I don't know why you are so indignant about this. I'm not insulting your personal choice. The rMBP 13 is generally a better computer for the following reasons:
1) It is SLIGHTLY faster than the MBA
2) It has a much better screen (albeit native retina resolution is only 1280x800 - I know it can be changed)
3) It can have 16GB RAM - quite an advantage in my book
4) It has more ports (can run 3 external screens easily, or use Ethernet/Firewire Thunderbolt adapters plus external screens)
It's also more expensive, heavier and has a shorter battery life.
My argument is not about it's other features, just the basic performance of the CPU.

Irrelevant, you said macbook pro and did not designate which ones. The fact is that ALL models of macbook pro's (retina, which you mentioned) are more powerful than ALL models of the air line. Period. That alone makes your statement completely false. They are NOT remotely air's with a retina screen.
Whatever, dude. I'd agree that the MBA and rMBP 13 are different, and that the rMBP 13 is a slightly more powerful computer in raw CPU (by about 10% at the top end).
The choice of rMBP 13 and MBA should NOT be made on CPU alone. It's the other features that should drive the decision.
I was weighing this up myself a year ago when I was travelling all of the time: I had to decide whether to get a really lightweight computer that I could use to work remotely (without power) for a whole day, or a slightly more powerful and expensive one that probably wouldn't get through a day's work without power. I chose the Air, but recognise it's limitations - I really wish I had 16GB RAM and another TB port.
If I get a rMBP, it will be an rMBP 15 which is clearly going to be an advantage in processing power. The rMBP 13 just isn't enough of an improvement to justify the expense.
My view is that the current rMBP and MBA lines will merge at some point with the rMBP becoming more "Air-like" in size and battery life (may with Skylake). The MBA may become a smaller low power option powered by Broadwell Core M or even ARM.
I would definitely get a lighter rMBP with 10+ hour battery life and a native 1440x900 retina screen (i.e. same resolutions as the rMBP 15).
