I am looking to buy a laptop for software development in the 0 to $2000 (USD) range.

What I am looking for: 1. Durability: battery life is important to me as well as general longevity of the hardware i.e. I would like it to last a long time.

2. Linux support: I use Linux as my OS of choice and I have no intention of using Windows/MacOS

3. Optimized for intensive computing usage.

Other things of note:

I looked into the Framework laptops and so far it looks like they are still a bit beta.

However, I am curious about users' experiences with:

* the KDE Slimbook 15: https://slimbook.es/en/store/slimbook-kde/kde-slimbook-15-comprar

* the Purism Librem 14: https://puri.sm/products/librem-14/

* Kubuntu Focus: https://kfocus.org/order/order-m2.html

* the StarBook 14-inch – Star Labs®: https://starlabs.systems/pages/starbook

Also tips about maintaining battery life would be appreciated. I've read too much conflicting advice about that lately :) Thanks.
