I bought a Lenovo X490S recently as a lightweight portable machine for writing on (great keyboard). It came with Windows, but as I Know Things, I immediately installed Debian. Worked fine, but didn't play well with my Apple stuff. Yes, I used the Gnome Connect thing, and various other hacks to get access to iCloud calendar, but it was all clunky.
The OS was fine, and Gnome is basically MacOS GUI without the recent madness, but the functionality was just poor. For example, encrypting a partition was very painful. You can encrypt the entire disk if you do so at installation (too late to do it later if you forget), but that makes resume-from-hibernate problematic. And recovery. Not impossible, just tedious. The IME was terrible (a known issue with Gnome / Wayland) and so on. Gnome looks lovely, but the whole "go to a website to install an extension if you want to edit the layout at all" thing makes Apple's walled-garden seem a model of liberal openness.
It was just painful to use. I started using Unix in the 1980s so I am completely comfortable with the OS, but there is more to using a computer for actual work than watching the RAM usage.
So, I reinstalled Windows 11 Pro. I had to spend all morning de-bloating it. Getting rid of the telemetry, adverts, pop ups and intrusive widgets. There are scripts out there that can do this for you if you prefer. If you leave it "as is", all these background things consume memory and ignore your privacy too.
BUT
If you switch them all off and replace the MS default apps (Edge, Outlook, etc) with the open source ones you'd use on Linux, I found Windows 11 Pro consumed no more memory than Debian/Gnome. Really.
And it is SO much better integrated with the Apple universe. My iPhone messages and calls come through, just as they do on my Macs. iCloud works just like it does on my Macs. Even my Photos library (master being on my Mac) is visible in the default MS Photos app. The IME is perfect. Sleep/Hibernate/Resume all function boringly reliably with no boot option hacking required. The disk is encrypted and I don't get asked for a password at each boot.
Oh, and it has 8GB soldered RAM. It's enough for my Mail, Signal, Line, Firefox, Open Office and Affinity stuff to all run at once. If it ever swaps, I don't notice it.
Dare I say it... it just works.
