Am I also suppose to mount a huge magnifying glass in front of it so I can see bigger?
resolution =/= screen size
???
I'm 45 and I am still (ditched the 17" in 2012 for the rMBP and haven't looked back) blown away by the phenomenal and incredibly sharp display of my 15" rMBPs. I own two, a 2012 and the CTO 2015 2.8/16/1TB - while the '12 is still incredibly well behaved and performance hasn't Missed a beat, the 2015's storage is four times the speed and a TB along with the iGPU updates to the IrisPro & AMD GPU's double the vRAM along with Thunderbolt 2, and the ability to drive 4 & 5K displays, the 2011 is an ancient computer now ...when I use it.
SATA compatibility, dead. All OEMs are moving to PCIe lane and connection access. SATA saturates at 500-550Mb/s, while my 2015 reads at 2,100Mb/s and reads at 1,850. HiDPI scaling on OS X has matured along with apps, even legacy software and browsers. It's almost two pounds lighter and doubles your speed, productivity and time spent waiting on transfers, updates of installs. 17" was nice but 17" in a 15" body is nicer and has the ability to run large displays that dwarf a 17" ...along with the radical user improvements you'll enjoy 3-500% efficiency and battery life along with a lighter load 'cause the charger can stay home without concern for power, the brightness slider and it's (laptop's) longevity
My 2017" is still in tertiary use with my business and plans going forward include the 15" model, their faster 'everything' with battery life, the weight savings, display quality and improved I/O, as well as nearly any other usage and tasks or workflow I'm aware of. Seriously, I was just like yourself and wasn't hearing it. The last MBP I would own was the 17 ... until I bought my bride her 15" rMBP.
I think it took me a half hour, maybe ten minutes and I'd forgotten any and all attributes I'd associated with my 12 years of 17" ownership of laptop computers
Then check this out ...you're gonna P00P yourself when you turn your new 15" rMBP on! (I use glasses, cheaters FWIW, so I'm no longer booting from the toilet)
The other thing is that you eventually get older and you won't see as well. Cheaters from Walmart for a $5 bill and life is good, so long as you're using a 'retina'or HiDPI display. While an incredible display for its day ('11, 17" 1920/1200), it's been improved upon by four, maybe five -taking mobile into account - years/generations by Apple, graphic power progressed through the same time as software and operating systems
Assuming Apple stays the course,,so will I. The 17" comes out, I'll be in line
Til then, the industry shrank bro
It's essentially ubiquitous with a couple outliers. None with the quality of Apple
I agree with brand

PS, they're all quad core and all include 16GB of faster RAM, no need for a price increase as it's 'stock' with the other two concerns you mentioned
