Your issues about the touch bar are the reason I bought the non touch bar version, I use function keys too much to have the physical ones gone, also I'd rather not have it go to sleep and prefer to have the bigger battery. EDIT: just adding that I did spend time testing the touch bar version in the Apple store as the price difference was not a major factor for this type of one time purchase for me, and I think if it's a good idea to do so if you live near one.
You seem confused. The default/native resolution IS Retina.
Retina is exactly about trading "extra screen real estate for image quality".
There's no "change", that was what Retina was about all along.
The other mode doesn't make much sense -- to have larger dpi but tiny screen elements on 15" or 13" screen, and scalable doesn't work as well with legacy apps and most stuff than "pixel doubling" does.
15.4-inch (diagonal) LED-backlit display with IPS technology; 2880-by-1800 native resolution at 220 pixels per inch with support for millions of colors
-- and lists a number of supported "scaled" resolutions.
I wonder why they made this move... People asking them for more real estate? Haven't gotten my MBPr yet, is the scaled resolutions workable?
I'd also add that the battery life is pretty woeful compared to a 13"MBA, I can't get more than 2 hours meaningful work done on mine.
The touchbar at time is slow and stutters.
The touch pad is too big and very often gets spurious inputs when typing. It acts like a "good PC touch pad", not the perfection of only a generation ago.
Power management with external monitors is also hit and miss. The device will often not wake in closed lid mode with presses to the keyboard.
The inclusion of Touch ID is great but whatever changes done under ttt hood has turned searching Keychain manager into molasses.
All in all this is the worst Mac laptop I've ever purchased, and I've purchased 1-2 per year since 2000. The only thing keeping me on the hardware is OS X.
I have to say M$'s new hardware looks very tempting.
a) Touch Bar reacting to fingers that are accidentally touch it while resting. Causes a lot of volume and Esc triggers. Latter is particularly annoying at it usually cleans Slack/Skype/other active text input.
b) Keyboard quality is terrible. My work machine does not respond to Option and Control presses anymore. My wife's machine has similar issues with up/down arrows.
c) I don't get why Apple changed default/native resolution to be non-retina trading extra screen real estate for image quality.
b) Last but certainly not least as mentioned on all previous MacBook threads starting October 2016: running Docker/minikube/Chrome/Slack and et voila: you have 4GB of RAM left. I'm not even talking about ML/Data Science work: AMD GPUs are way behind even 1050 at the moment and I doubt that their new offering that is meant to compete with nVidia P100 will ever make it into a laptop.
Personally I think this news isn't real. Intel "promises" to release Cannonlake this year (thanks, AMD!) and I don't see much sense in either updating MacBooks with Kaby Lake nor releasing them just after 8 months after last refresh. That's the CPU that you get when company stops trying.
If they are going to mention MacBook Pro, I'd probably expect them to do a small price drop but not a refresh.
