It seems you are living in a silo, because if you've seen what the competitors offer, its quite apparent that Apple laptops are nothing special.
This is 2016, competitors have got ahead of Apple laptops - better value for money. Apple have fallen behind - read through the posts, a lot of people feel this way. We will see what Apple release in WWDC. I hope the refreshes are *Good*.
Firstly, Keyboard - Your really trying to say the Apple laptop keyboard is Premium? Really - what is Premium about the Apple laptop keyboard? You answer me that, thanks.
Battery life - is nothing special.. a lot competitors offer the same.
Software - we are talking hardware, not software. ( OSX is good , as is Windows 10 )
Build Quality - Good better than others.
Connectivity is nothing special.. go look at the competitors, they also offer *exactly* the same connectivity as Apple. Bluetooth 4, TB, USB3 - these are no big deal in 2016. Some competitors offer USB3.1 in their latest and greatest .
What does it matter about Build Quality if the components of the machine are nothing special? Your wrapping a pig in nice clothes! Lipstick on a pig.
So Build quality and SSD maybe better than average.. still, doesn't justify higher prices. Macbook Pro is not a premium product vs what else is out there. Sure, you'll think otherwise.
You buy your over priced "Premium Product" Macbook Pro 2015 - I'm certainly not. If Apple can't can't provide Good Value For Money, there are better products out there.
