But, I don't like that ads are in the start menu, that I'm asked to try out Microsoft Edge, or that the built-in search checks the web rather than sticking to my PC.
There's a lot of small points of friction, and it seems that after every major update a new one is added, or my old preferences are ignored. For many of these settings, you need to go into less familiar tools like the group policy editor as opposed to the built-in Settings app.
It feels gross to have paid $200 for a Windows 11 Pro license to then be shoved ads.
Apple is just as bad, routinely having a notification offering me a trial of Apple Fitness even though there is no way I would ever buy that because there is no way I'm going to pay 10 euros a month to have workout planning to use an Apple Watch I already bought from them for a decent amount of money (devices in this price range have this type of stuff built-in).
As far as I'm concerned, Microsoft gets a small pass for the nagging, because at least I didn't even spend a lot of money with them since I didn't buy my windows computer from them.
But Apple is a big no-no. No way you upsell me after selling me a deeply flawed device (partly because the software is an unfocused mess and lacking in many ways, partly because the hardware is not that good for the price).
I would imagine support might not be 1:1 with all the features as Windows 11 might support, but probably good enough. It'd be a sacrifice I'd be willing to live with.
And then there's booting. You will probably have to monkey with secure boot, which means dual booting can be a pain. Big, popular distros are starting to support secure boot, so it might just work, but it might not. And I'd be kind of shocked if MS didn't take the opportunity to ditch legacy x86 baggage[1] to completely lock down boot and make it impossible to run anything but Windows.
In summary, on older Surface devices, yes you can run Linux but you have to pretend it's 20 years ago and Linux is still a pain to get running. On ARM? Good luck.
