I am typing this on a 2013 Retina 2.7 w/16Gb.
I did not entirely buy it for the more or less 3% price difference with an HP/Dell.
I bought it because of everything else it does better and being more integrated than a Windows 7 / Windows 8.x laptop and the 5 to 7 hour battery life.
Your belief that a Pro is too expensive is not accurate when you compare the 512Gb SSD, 16Gb ram, 802.11 ac, 2 * 10Gb Thunderbolt ports to any other ( who else makes a comparable device ? ) vendors platforms.
I am a network engineer with multiple 10G network core and edge environments, please tell me who else makes a laptop that I can attach 2 10Gb adapters and do data capture at wire speed ?
And I want 2K+ graphics on my desktop monitor while at the same time having retina level quality on my laptop.
any one ?
No, I couldn't find one either. Pseudo comparable HP Z series laptops have spinning disk, 4 Gb ram, single 1Gb NIC and run $2800. Adding Retina level display to an HP costs $600 and a 512Gb SSD is not even an option - the largest HP SSD is 256Gb.
Formula F1 cars may be expensive, but for the people who know how to use them correctly - they are worth every penny.
