I bought laptop in october( 2015) its the best gadget I've ever owned.
Display-
Not only the retina display is crispy enough but the color accuracy are on point. Watching movies and coding feels great!
Speakers-
The 15in rMBP 2015 has crispy stereo speakers they are loud enough to fill the enitre room and are elegantly placed
Performance
The baseline 15in came with PCIe based ssd and believe me blackmagic speed test revealed the writing speed of 1.8GBps and 1.2GBps which is jawdropping! It is again coupled with 16gb ram, 4th gen i7 with higher wattage then usual for better performance.Even after 5 hours of editing on photoshop the fans don't turn on like windows machine.
Design-
The macbook is elegantly crafted out of a single piece of aluminum and its worth every penny in that 1.5lakh price tag.The fans are asymmetic inside and therefore fan noise is reduced by 80%, speaker grills are diamond drilled for perfection.You can lift the lid/flap of this laptop with one single finger! something that shows how high quality the construction is!
Other perks of owning a mac -
Force touch trackpad( its epic! every other trackpad feels like antique product from the 80s after using force touch)
One of the best backlight keyboard
No bloatware( seriously MS added stuff like alarm clock and stopwatch in windows 10.mqc on the other hand has useful stuff)
No virus( although malware can affect mac os x)
Beautifully designed OS
Apple care for 1 year( free)
Heavily optimised software
Crafted materials( no body other than apple cares about design. Everyone uses cheap plastics and part of aluminum but apple uses only premium materials like unibody aluminum and glass)
