Well, you're referring to the MSRP, hence you are somewhat correct. However, would you have taken the time to read my previous post, you would've noticed that I clearly stated that the 13" MBA and cMBP are the volume-sellers, hence why they sell at great discounts at our equivalents of Best Buy. The store I'm referring to is Elgiganten, which sells the 13" MBA for 8990kr. Comparing Apples to Apples, the same store sells the rMBP for 11990kr. A difference of an equivalent of 459 USD to be exact. Based on the swedish pricing, the rMBP is 33 % more expensive than the MBA.
Sure, one could argue that the rMBP will probably drop in price, as soon as the cMBP is discontinued. I for one hope that this will be the case.
However, I'm not going to continue this discussion, mostly due to the fact that most members of MR could care less about our local pricing, that said, heck, even the $300 price difference you mention is a lot for most students.
Point is, I'd love to see Apple offer a larger-than-12" retina MBA, at a competitive price point.
