Did I make a mistake purchasing a PC with Optane memory?
I currently have a laptop that is about two years old, and has 8 GB of RAM. I use my laptop for internet browsing, productivity applications, and programming, including data science within Spyder or RStudio.
I usually sit around 65% memory usage, or 5 GB roughly.
I recently purchased, but haven't yet received, a laptop which has 4 GB of standard RAM, and 16 GB of Intel Optane memory. The laptop was marketed as having 20 GB of RAM, but after reading more about Optane memory, it seems that it serves more as a low-latency cache than as RAM.
Is it unwise to get a laptop that has less actual RAM that my average usage, even if it has copious amounts of Optane memory?
Here's a snapshot of my current memory profile if it's helpful:

Intel Optane "memory" is a misnomer. It is just a cache memory card that can turn
a simple hard disk into a hybrid disk, by adding a RAM cache that can work at the
speed of an SSD disk.
Optane memory isn’t a random-access computer memory, or RAM.
Instead, it's meant to work as a cache memory bridge between RAM and storage,
allowing for faster data transfer between the memory, storage, and processor.
As such, it's magnitudes faster than a spinning hard drive and can work at the
speed of a budget SSD. And like SSD, it doesn’t erase itself when powered off.
Conclusion: You did make a mistake by falling for a commercial hype.
In addition, 4 GB of RAM is ridiculously low in our current state of hardware
and software. I would advise canceling the order for this laptop,
if you still can.

Although I don't completely agree with the first part of Harry's answer, I do agree with the overall message. In your case, I would imagine the laptop will not have the performance you were tricked into believing it has. Optane is not a replacement for traditional RAM.

The part about it turning your conventional drive into a hybrid disk. I know what you mean but I think the description is slightly oversimplified. Optane does a lot more than just cache (part of your) storage data.

Good answer. +1. Additionally, I would like to suggest this article, which compares access speeds to human reference scale, from 1 clock cycle -> 1 second, RAM -> 4 minutes and Optane -> 7 hours. This really shows how much scale difference there is between for example L1 cache and disk access speeds...
