What do you mean durable? As long as you are careful, and don’t use it as a frisbee, any laptop can last for 10 years. If you travel about with it, get a proper laptop shoulder bag that fits it well and has a soft padded interior. Then keep the laptop in that when you travel, and don’t squash it into a bag or suitcase.

Beyond that, simply look for the laptop that you like best. The Thinkpad is a meme laptop IMO. I had one for work, and yes it worked fine with Linux, but so did both the laptops I bought for myself, neither of which were Thinkpads. If you like the look of the Thinkpad, then go for it. Personally I don’t really dig that clunky 90s aesthetic, I prefer laptops with a sleek minimalist aluminium look.

My advice is to make a checklist of everything you need and/or want in your laptop. How long do you want it to run on battery? What size screen do you want? What connectivity does it need - USB-C ports, a couple of USB-A as well? Do you want it to use a USB-C charger (this is very convenient when travelling)? What kind of touchpad, keyboard layout, how much RAM, what speed WiFi etc etc

Then simply start looking, and build a shortlist of laptops that appeal. Create a spreadsheet, with a column for each of the features you identified as being important in the last step.

Regarding Linux support, the best thing you can do is check reviews. Even if you buy elsewhere, Amazon reviews are great for this - you can search reviews for keywords, so when you see a laptop you like the look of, search for reviews that mention Linux, and check that everyone’s happy and not complaining about unsupported devices. This is not the lucky dip that it used to be, but there are still problematic components like network adapters that may not work out of the box.

I have only had two laptops, the first of which I bought in 2018. It was an Asus, very midrange at £600. I prepared a live USB, booted on to it and checked everything worked OK, which it did, and then without further ado I installed Linux. The sensible thing to do would be to have left the “Windows rescue partition” intact for a couple of weeks until I was sure I was happy with the machine, but I just wanted all trace of Microshit purged from my shiny new machine, so I deleted it and set the entire disk as my single Linux partition (plus of course a small boot partition), and I never looked back.

The computer worked great, did everything I needed from it and was still going strong last year when I finally got a replacement. The laptop I have now is a Lenovo IdeaPad 5. It was also £600, and its performance is way better than expected, being way faster and more pleasant to use than my old Asus. it has an integrated Intel Arc graphics card, which is surprisingly capable. While my old laptop could only run vintage games, such as KOTOR, this new one is able to run current games on medium-low settings. I’ve currently got addicted to ARC Raiders, and it runs perfectly acceptably. Nothing like as smooth and pretty as it runs on my desktop PC at home, but perfectly good enough for me.
