I have a 2011 MacBook Pro 17” and have upgraded it with an SSD and 16GB ram. So now even 6 years later I can’t see anything even on the horizon that makes for a killer upgrade. Especially considering it would need to be worth losing 2” of screen.
Is there anything awesome coming in 2018 to the MBP or even 2019/2020 ?
DONT DO IT! IT'S A TRAP

.
Switched from a 17"fully loaded macbook pro ( 16gb ram / ssd / bluetooth 4 card / new mainboard ) to the 2016 Touchbar 15" and it simply sucks.
I work as a freelance designer and the "spec bump" is barely noticeable:
- 2.7ghz vs 2.1ghz i7? ..unless you do video editing , no change whatsoever
- 16gb 2133 ram vs 16gb 1333 ram ? nop , nothing .
- Radeon 455 vs 6750M ? Didnt play games , ive got a PC/console for that ...
- Retina 15 inch vs 17 inch full hd ? Personally i prefer the 17 inch size . Couldn't care less of the billions of pixels , bla bla ... marketing ******** of the new screen .
- Brightness of the screen ? again ...who the hell uses the laptop on full brightness anyway ? i was using my 17 on 90% slider , now im using the 15 on 60-70 to achieve the same level .
- battery life ? debatable .. I used to get around 2-2.5h of photoshop with the 17". im geting around 3-4.5h with the 15". However i did get around 8h of safari netflix binge watching with the brightness set to around 60-70% ( i guess thats womething ? )
- Touchbar ? i simply set it do display the old controls all the time ( basically disable it ) as it didnt provide anything useful
- Touch id ? its good , but not a deal breaker
- Weight ? HELL YES . i love how light the new one is compared to the 17 inch one . However i do wonder if apple made a 17inch mbp today ...how heavy would it be compared to the 15" one .. maybe 400g more ?
- Ports ? welcome to the dongle life! for a laptop that was suppose to make life cable free , this ****ing machine needs a ton of cables ! Ive purchased a hub at home and it looks like cable nightmare.
-Trackpad ? Its not that bad , i actually like it, but its a personal preference
- butterfly keyboard ? Compared to the 17"one ? Oh god why !!! its so damn clickyyyyyy and just weird to type on. I was pressing so hard on it i thought i would break it .
The only reason i gave up on my 2011 17" mbp was the fear of having another issue with the graphics card. I changed the mainboard with apples replacement program about a year prior and the screen was starting to make those weird lines again. Knowing it would cost me ~800eur to replace it again .. i was forced to buy a new mbp. I got a super sweet deal on the touchbar one , but if i had to pay full retail price , it's really not worth it .Get a 2015 one instead
Offtopic :
How hard would it be to 3dprint / manufacture a 17" chassis that fits the mainboard / battery / keyboard ( all the internals ) of a 13 / 15 touchbar macbook pro ?
