Valve had a Steam Machine before the Steam Deck which went down like a lead balloon but did get enough indie interest to continue to support a Linux version of the client. The Steam Deck is basically a continuation of that in a small form factor. I wouldn’t be surprised if Valve ever decide to offer cloud gaming that it is also derives from some of these efforts, if for no other reason than to avoid a Windows license fee on the server.
The weird thing to me whenever anyone complains how much memory a browser takes up, is what do they think the free RAM is doing otherwise? It’s free so why can’t an application use it? And that’s what browsers do, taking the memory to use as a cache, and releasing it back to the system if available memory dips below some threshold.
And downloading updates is a good thing. Means that the fresh installation isn’t vulnerable to something that was fixed between when the USB / DVD was pressed and the time the person installed it.
Linux has made leaps and bounds with usability and ease of installation but it’s no better than any other modern OS - which is a good thing. Installing Windows from a USB stick is not difficult - the simple path is literally, pick a language, select your wifi, choose who is logging in, click install and go grab a coffee. About the only difficulty if you can call it one is that some installs will ask for a serial number because it’s a commercial product.
Also, the number of questions & buttons during installation is one thing but the certainty of a functioning system is another. Linux is better at supporting old hardware, Windows is better at supporting new hardware. Choose accordingly if that matters.
I don’t even know what this graph is even supposed to mean. Bitch about Windows all you like but the installation process is typically very simple.
Ubuntu. There are mixes of it but out of the box Ubuntu is about as straightforward a dist to install as possible and it is well supported.
That said “new laptop” and Linux are not always a match made in heaven. You might try it from a boot stick and confirm that things like the GPU, touch screen, touchpad, fingerprint reader, USB C / Lightning all work properly.
