No sarcasm. I'm genuinely curious about it.
You gotta admit that most customers would take the former over the latter though. Less than 1% of their user-base needs a laptop with 128+GB of RAM.
"Pro" on the laptop line no longer has the same meaning as "Pro" on the desktop line.
It used to mean "workstation class" on both lines. "Workstation class" meant that you had more upgradeability and performance options. "Pro" as it relates to Macbooks simply means "premium". There's nothing wrong with premium, the Macbook Pros are still very performant, but you're going to lose the people who put high value on what "Pro" used to mean for Apple laptops.
If you look at Dell, Lenovo and others, they offer "workstation" class laptops for their "pro" markets. They're not the highest volume sellers, but they don't alienate any of those users by forcing them to switch to their "premium" business laptops.
