Redesign lover here.
Thinner is a huge part of it. I am a huge lover of the MacBook Pro. I use one everyday. But Honestly, every time I use it I cringe because it is so thick. Call me crazy. And I know its pointless to wish for a magical device that is paper thin had tons of battery and tons of features and performance. But I know that it can be thinner, there are other notebooks with 28W Cpus that are thinner and still have sufficient battey life. Also it has been 4 years since the last redesign so Apple must have more tricks to cooling devices batter and optimizing battery.
Honestly, if Apple slapped a skylake CPU, forcetouch, new retina Display in the MacBook Air, even if its only like 2304x1440. I would hugely HUGELY prefer that machine to the MacBook Pro. I would never get the Macbook air as my primary now because that old screen is a deal breaker. I understand that it is a good chance Apple will never update the MacBook Air anymore.
Or if you made the rMacBook slightly thicker enough to add a 15W CPU and fan, and then a USB-A port, that would be my notebook of choice.
In reality, I know whenever the next MBP redesign is, it won't be able to get very much thinner if they choose to keep same processors, and not too sacrifice battery.
And then finally color options are big for me as well. Even though they don't affect performance a space grey MBP would be so cool to me, I also like gold too.
And yea, smaller bezels would be awesome too.
Yes that is correct. the 950M actually uses just over 50W I heard.
Therefore makes sense to use Iris Pro, because same or better performance. And much less power consumption, and heat, and size.
However, if Apple was to wait for Polaris/Pascal. Then it would make sense to use those, since they will have even faster performance and DX12 support
