I just put 64 gigs of (fast) memory and a (very fast) 4 TB SSD in my laptop for a total of $600.

In the MacBook Pro configurator the equivalent upgrades look like

36GB->64GB RAM: $400

1TB->4TB SSD: $1000

Except you can't upgrade Macs anymore, you need to buy a completely new one.

Same goes for PCs sadly. Soldered on RAM is becoming the norm -- even Lenovo does that on their high-end ThinkPads.
