I kind of understand the OP although I don't agree 100%
I think retina screens are a big enough technological challenge that Apple had to design a new macbook pro rather than just add it to the old ones. The increase in battery etc. made it necessary. And honestly we never would have seen some of the other improvements (HDMI out new cooling design) without a completely new model. I have no issue with Apple coming out with retina Macbook Pros as a new model and I can even understand the price increase up to a point (should have had 256gb in the base 13inch rMBP).
BUT
What I do take issue with and what I think some others on this forum are annoyed with is Apple usually their amazing marketing hype to make retina the new gold-standard of what people should want in laptop computers.
Think about it...before everyone was working towards shoving the most computing power into the smallest package with the longest battery life. But Apple (and subsequently the rest of the industry) realized increasing computing power was starting to have diminishing returns. Average consumers just don't need it.
I actually really like that Apple focuses on the whole package with their notebooks. They make sure you get a great trackpad, good battery life, solid chassis and now fast storage in your laptop. But now they seem to being doing with resolution what the rest of the industry was doing with cpu usage. Aka giving the consumer way more pixels than they could ever possibly appreciate which would be fine except that it comes with draw backs in both performance and battery life.
The 13inch rMBP with a 1440x900 IPS display, slightly more storage and a slightly lower price tag would be a GREAT machine for far more users than the retina MBP we have now. It would have less issues with app compatibility, better battery life, and no software hiccups with the UI. But Apple is counting on the wonderful marketing of "retina" to upsell a lot of people on a computer that is essentially a regular 13inch MBP with that screen and charge a huge premium for it.
Now of course that is Apple's business and as the consumer really all you can do is buy the computer or not buy it. Just though I'd through in my 2 cents
