For me the laptop must have at least these minimum features if money is no objection:
1) Weight about 1 kg. I do carry another e-ink reader in my bag thus a lighter laptop is a big plus.
2) Minimum 2K resolution. Once you have used 2K screen the Full HD just don't cut it anymore.
3) Military grade certification for drop. I once dropped my laptop bag from shoulder height containing less than a month laptop but because it has military grade for drop it did survived (albeit some scratches) until more than 2 years later, today.
4) At least 128 GB RAM (preferably ECC) if I am buying a new laptop because you can never has enough RAM :-)
"2K resolution is a generic term for display devices or content having horizontal resolution of approximately 2,000 pixels." (...) 1920 × 1080 is the most common 2K resolution"[0]. How are you distinguishing between 2K and 1080p?.. are you thinking of 1440p (2.5k wide), or of a non 16:9 aspect ratio?
Have you ever found a laptop like this? 1kg is sacrifice a lot of corners in the name of weight (battery, screen, glass, ram, cooling, drives, processing and GPU), while workstations are are the likely place to find 128GB ECC.. they focus on performance over weight (they're getting better at style). Sounds like you want a workstation laptop in a ultrabook's body (and who doesn't.. I think there's a guy at NASA that would like you to bring it in for study)
Yes for me 2K is QHD or 1440p. It just easy for me to compare display resolutions for example 0.5K for 720p, 1K for 1080p, 2K 1440p, then 4K, 6K, 8K, 16K, etc [1]. Buying laptop with less than 1440p display today is just beyond me.
They are many 1 kg laptops around at the moment by most of laptop manufacturers. For GPU personally I have an external GPU or eGPU via Thunderbolt interface.
Currently they are many laptops 128 GB RAM around, they just need to put it in a lighter laptop based on i7 or i9 [2]. Heck even the cheaper Intel's 10th Gen Celeron CPU can support up to 128 GB RAM [3]. It is not a rocket science to put 128 GB RAM inside a lightweight laptop today.
[1] 720p vs 1080p vs 1440p vs 4K vs 8K – Which Should I Choose?
You are using that display terminology differently from everyone else. 2K, 4K, etc. refer to horizontal resolution, and 720p, 1080p, etc. refer to vertical resolution. 0.5K would be something like 512x384, an ancient resolution lower than VGA (I used it sometimes in the 1990s), and definitely not 720p, which is 1280x720. 2K, 4K etc. came from cinema and filmmaking, but 720p, 1080p etc. come from TV and computers; the "p" stands for "progressive scan", contrasting with "i" for "interlaced" (a lot of HD TV broadcasts are 1080i).
Not sure you are trolling or not, but I will bite. One of the very RAM intensive stuff I'm doing with my laptop is that I am using many VMs in GNS3 set up for networking simulation with Linux VMs running Quagga, LiSA, etc thus the more RAM I have the faster and smoother the simulation.
Why so many people go berserk when you say you need more RAM? The new workstation CPU from Intel namely W3300 can support up to 4 TB RAM, RAM amount of 128 GB is practically peanut compared to that.
