> 2. States that only laptops with 32GB is as heavy as 17 pounds and bulky. But Dell XPS 15 comes with 32 GB and weighs only 4.5 pounds.

That point blew my mind, too. I have 32 GB RAM in a 6 pound laptop (a third of that 8 kg beast presented by the author)... and it's from 2011! If somebody rewrite some BIOS parts, it would even take 64 GB (4x16 GB modules). Yes, not many laptops have four slots, and certainly not the ultrathin ones, but even with two slots, 32 GB is easily possible as 2x16 GB (available both in DDR3 and DDR4) and no 17 pound gaming monster is needed at all.

The battery capacity also seems moot. More memory modules draw more power, that is sure, but in terms of laptops with 74 Wh batteries, it is a negligible decrease of battery life, especially if people who need and would order 32 GB RAM would easily sacrifice some battery life (at load) if they can get more of their work done significantly faster without swapping.

Also, does the new MacBook Pro actually use only a single module? Because you get the power consumption increases when you add modules. If it internally uses two modules of 8 GB to get 16 GB, then using two 16 GB modules instead would use the same power, unless I'm missing something (the memory is soldered on, so the entire thing may work differently than typical SO-DIMMs).
