Interesting comment I read about the Retina display in browsing context. This is true that many websites can't display well at 4x what was considered a high resolution a few months before. However, how does the Mac scales everything to keep it readable? Working mostly on texts, sometimes with very small characters, Retina would surely make a huge difference.
On the other hand, I wish they won't let the "classic" MBP down. RAM is not upgradeable in the Retina models, and I couldn't do without my 16GB, that is not even available as an option from Apple. For the sake of speed, they reduced the base storage available three fold. There is no way I could get as much horsepower in a Retina MBP 13" than I have in my "classic" 13" MBP. External storage may only do the job to a point, since having a laptop, at least for me, implies being away from said media for length of time. Home internet connections are just not fast enough to serve high quality media over the Internet, and wifi coverage is still full of holed. andy9l, until said challenges are solved, there's nothing that could comfortably replace large storage capacity. Such capacities are still not available in SSDs.
Unfortunately, the trend seem to be not caring for people who need to get heavy work done on Apple's machines: Mac Pro has yet to see an update, MacBook Pro Retina favors thinness above upgradeability, iMac, same. Granted, many customers seem to be clueless spoiled college girls
What baffles me is how they crammed a higher capacity battery inside similar-sized Retina and "classic" models, but still got the exact same runtime.
