Glad to see that there are laptops that don't suffer like this. But I think the combo of having a steam deck + business laptop beats buying a gaming laptop. Assuming you already own a gaming rig at home.
Never again. A laptop with a dGPU runs counter to the things a laptop should be. Keeping gaming activities on a desktop is the best option in my experience.
A few months ago, I started working at an e-waste recycling company, and discovered that used Microsoft Surface tablets are what I've been looking for. My work "laptop" is a Surface Pro 5 with Debian (my work desktop is an Optiplex micro). I'm typing this on a Surface Go (with BlissOS) that I bought for myself. The cameras don't work on either and the work Surface never knows it's battery status, but I don't care (it lasts an entire afternoon with a barcode scanner, good enough for me).
If you don't like a dGPU in a laptop, that's fine. But people have different needs. I travel a lot and do 3d content creation work.
I've had 2 now from different manufacturers and the firmware seems alright due to the integrated nature of the API making them all fairly homogenous.
Also, comparing a steamdeck to a modern gaming laptop is like comparing a $1 water pistol to a super soaker.
