Samsung has quietly added 32 GB unbuffered DDR4 memory modules to its lineup of products. The UDIMMs are based on the company’s 16 Gb chips, which were introduced earlier this year that are already used for 32 GB SO-DIMMs as well as 64 GB RDIMMs.
Samsung’s 32 GB UDIMM is rated to operate at DDR4-2666 date rates at the DDR4 standard voltage of 1.2 V. Samsung does not disclose timings, but since the company sells its own memory modules mainly to large PC OEMs, it is highly likely that the 32 GB UDIMM uses the standard JEDEC latencies for DDR4-2666 (i.e., CL17 17-17 or higher).
[...] modules that use these DRAMs are more energy efficient than DIMMs of the same capacity that rely on a larger number of 8 Gb devices.

I loved Samsung's magic RAM back in the day.... 4GB sticks for $20. No fancy heat spreaders or LED lighting, they just worked great and were cheap.
So that was many years ago. I'm sure these new 32GB sticks are probably just as cheap these days, right guys? $20 is a good price point for 32GB of RAM to have fallen to after a decade, right?

Your point is well taken. Value important no, removing "owner's*" ability to root very important.

* If somebody else has root and you don't, you're not the owner, whatever your receipt may say. Possession is nine tenths and all that, and they possess root (control) of the device; you don't.

The price of TI calculators will never come down because of how they've been allowed to be integrated into maths teaching in the US.
Don't have a TI-83? Fuck you, cheater. Automatic zero.

Given that RAM capacities rise and rise and rise, I find it odd that computers that I am interested in buying are so limited in RAM options...
I'd really like to see 8GB as the minimum on things like this. These aren't super efficient embedded boards designed to run on minimum power; they're multi-amp power ARM boards (comparatively). 16GB or 32GB even better. Having more RAM can help make up for the speed of their anemic ARM processors and make them much more suitable and pleasing as general purpose workstations for the privacy-and-freedom conscious geek.
They wanted to make the Odroid N1 [board-db.org] with a paltry 4GB of ram, but had to discontinue it before it ever saw wide production because the RAM chips weren't going to be available. Hello....

Many of those boards are limited by power. 32GB of these chips requires approximately 8 Watts of power based on my quick calculations from the specifications. For the machines you cited I calculated how much power these chips (just the chips) would take up of their total power budget and compared it to the current requirements using the same chip (although they are probably using 8Gb chips, so in real life the last column is probably between 1.5x and 2x more). Regardless, there is a chance you'll notice a pattern in the last column for the as-shipped version:
This also doesn't factor in the increased power requirements from other parts of the board to support this much memory on the board. It also doesn't consider the higher amount of cooling required as the TDP is also a bit higher, most likely due to the increased density. There are also other design limits, such as board size and layout, memory address bit depth and a few other things to consider. Suffice to say, anybody could design a system with more memory and power and storage, etc. but engineering is making a useful balance of all the costs and limits inherent in your project and its environment.

From what I understand, the processor itself is what limits the memory capacity of those boards. There are more factors than just the GB though - LPDDR vs DDR, DDR3 vs DDR4, ECC vs non-ECC, and any of those will make a substantial difference in performance.
