It is quite apparent that they don't otherwise the Mac Pro would have been updated a long time ago. Apple are for the middle ground and those who want a 'cool looking' computer that works.
I cannot see the MacBook Pro ever being close to workstation levels again [which I would like too]. They are a compromised solution for the majority, not the minority who need power. Dont forget Apple are really a consumer company who has their major profits elsewhere. Why would they make laptops that are for a minority, it just doesnt make business sense.
From realising the above last year, I settled on a iMac pro. It is a great machine but not very portable

A MBP is a compliment device to the desktop I feel, not for heavy work but for getting some stuff done on the move.
Its the same as an iPad compliments a laptop.
Yes I would spend $7k on a Mac laptop that is in a larger chassis with a great Nvidia GPU and a 6 core CPU. Sounds awesome, but we all know it will never happen...... off to Windows for those productive computers.
