The laptop I wish I had never bought, but I am glad I did.

Working in the tech space, I've had a myriad of Laptops which were just good enough. I wanted something a little better.

I've owned and used a plethora of Laptops over the years, all the brands, all the Types, from Windows 2 to Windows 11, Apple Macbooks, Chromebooks and even Android Devices baked into a Laptop form factor (Thanks, Asus)

Occasionally, like in 2020, I'd buy something like I did then, a Dell XPS with 16Gb of RAM when the standard was 8Gb, and push the boat out.

This LG Gram was one of those purchases. I wanted a top-end laptop. Something built well, something which would last the test of time, and I could run multiple virtual machines on different OS and not have to worry about RAM and CPU space.

This last one was of particular importance to me at the time as I was learning Kubernetes (and still am) and wanted a local cluster I could spin up and tear down to learn about projects.

The LG Gram I ended up buying was a laptop beast (in my eyes)

13th Gen Intel(R) Core(TM) i7-1360P

32Gb Ram

1Tb SSD Storage

17" Display

Light

And to be fair, it is a lovely laptop.

It came with Windows 11 Home, which I didn't even boot into and promptly installed a Linux Distro (Ubuntu 24.04) onto it. I've subsequently done this more than once, and I finally ended up on Arch-based Garuda Linux.

Linux runs like a dream on this laptop, mainly because it's Intel all the way under the hood, so there are drivers for everything baked into the distro.

I've been able to run up using Qemu and LVM a K8s test cluster with 4 devices of 4Gb of RAM and a 4 GB Rancher server and still have plenty of grunt under the hood to run the day-to-day

The problem (and it's a first-world problem) is that I don't need this amount of power.

I spent January working off my 4-year-old Google Pixel Go Chromebook. I could do 90% of what I needed to do on my Samsung tablet Desktop, and I have a Lenovo ThinkCentre sitting in the order of the room, running the services I need in the background (DNS, NAS, Media Server, etc.).

So, as a Laptop, the LG Gram has become my daily workhorse. It is the place where I tinker with Ollama, Spin up a Windows VM, or spin up a cluster of servers to try something out. It gets used for 8 hours a day and then put to sleep at night. I'd feel wrong turning it into some sort of server and not using it as a laptop, but I fear this is where I may end up.

Unless, of course, I find something which needs the power to run.
