What puzzles me is that every 2.4GHz reports 32GB of RAM, while every 2.3GHz has 16GB. I could understand it if these were stock configurations, but 32GB is not standard in the 2.4GHz. Also, I would have thought that the 32GB RAM option would be popular in the 2.3GHz model. Strange.
Anyone spending $3000+ on a laptop probably isn't penny pinching while they are looking at upgrades. Also, someone buying that 2.4 probably knows they need all the performance they can get, including extra RAM.
