The two are incredibly different though. It doesn't need a slide over for instance because it is a full desktop OS and I run it off a 27" 4k monitor. Who needs slide over with that? Even the 14 and 16 inch laptop screen has far more room.
Personally, I find Slide Over very useful in combo with the multi-windowing system on the iPad. As I have probably mentioned before, I used a MacBook before I bought an iPad, and so when I first picked up an iPad and discovered Slide Over, I really found Slide Over handy for quick access to messaging apps and such, and thought that would be really cool on macOS. The way it works on iPadOS 26 in combo with the multitasking system is a dream come true for me, it’s so nice to be able to keep utility siloed off-screen for quick access when needed. And it travels with me between stages in Stage Manager, which is also handy. 👍🏻. When I dock my iPad at my desktop monitor, I still use Slide Over, and the plus is, I can even setup a separate app in Slide Over on the monitor vs the app in Slide Over on the iPad’s native display, so that’s a nice additional touch. 👍🏻. I’m a big fan of the new Slide Over implementation, I can make it bigger or smaller depending on the app I’m using in Slide Over, and I can move it somewhere else on the display. 👍🏻 The only downside is it currently doesn’t support stacking multiple apps in Slide Over. But given the other major improvements, that’s a fairly minor downside in my opinion, though maybe they could add that ability back. 👍🏻
I think it is interesting that the people, like you, who seem to really like the new iPadOS also seem to mostly dislike desktop OSes. Personally that might be the delineation. I LOVE my desktop OSes and use them all. Linux, MacOS, Windows, and even some 'Nixes back in the day. These mobile OSes seem so confining. I can't even load anything not allowed by the store.
Yeah, I do find that interesting when you mention it that way. I do tend to find I don’t like desktop OSes as much as iPadOS, and find them to be less efficient in several areas for my preferences and workflow. Maybe it’s a generational thing. I know people talk about the file system, personally, I don’t see what practical difference it makes whether I can access OS system files or not. I know it probably benefits some use-cases, but it doesn’t impact my workflow at all. I’ve never found the Files app to be very different from Finder on the Mac in terms of utility, though it is really nice being able to pin folders into the App Dock on iPadOS 26. And I was very relieved to find you can still set Quick Look as default for previewing images in Files on iPadOS 26, something I can’t do on macOS, on macOS, it feels like I have to jump through hoops to just scroll through a folder of images. It’s little things like this that make a big difference cumulatively for me. 👍🏻.
Personally, I vastly prefer to be able to source all of my software from one secure place, and have one system for managing app updates. I actually find that to be a plus of iPadOS. When I install apps on my Mac, I try to use the App Store whenever I can. Sadly, some app developers don’t allow to me to install their apps from the App Store on the Mac, and force me to side load their app. In the App Store, it’s easy to find apps, there’s less security risks (not zero, but dramatically reduced thanks to Apple’s app review), and I can see what data the app collects. And app updates are handled via the App Store, and I can choose automatic or manual updates if I so choose. Where on the Mac, I often end up having to look up an app’s page, make sure it’s
actually that app’s real page and not a spoof page to trick users into installing a fake version loaded with malware, and there’s not really any way of ever knowing what kind of data the app collects. And every app has it’s own different system for handling app updates, and many don’t allow you to opt out of automatic app updates, they just update regardless of whether you want them to or not. And that is especially annoying when there’s an app I haven’t used in a while, but need to quickly for something, but instead of being able to just use it, it first has to take a minute or so to update. I get that on the Mac they support app side loading because they already supported it before the App Store concept, and I know some like or prefer app side loading, but I really think the App Store model is much better. That’s my opinion at least, YMMV. 🙂👍🏻
But yeah, I totally get others may disagree with my takes here, and I totally respect that others prefer desktop OSes. I would say, I’m actually not terribly surprised you find the Surface Pro to be a decent tablet experience. Windows 11 has made several improvements (read, they borrowed from Apple) that make Windows 11 feel a bit more tablet friendly, like the centered Task Bar design, more rounded edges, etc. I have an Asus Ally I use for some PC gaming. It’s got a 7” screen, but the scaling is not too bad. Many buttons and options within apps, however, are too small and closely spaced for me to tap precisely. So I definitely find the apps themselves tend to be more the limiting factor. But then again, I am using it on a 7” screen. Personally, I am very happy with the Xbox Mode introduced last fall, and haven’t used the desktop mode since. And everything is generally better scaled within the Xbox Mode, and I generally tend to navigate with the controller more than with the touchscreen. A family member of mine has an older Surface Pro X, and they really like it. I would also point out, Windows is kind of similar to iPadOS in several areas that macOS isn’t. App windows in Windows 11 typically open fullscreen by default. Images are previewed in a more Quick Look kind of thing that’s easier to scroll through a folder of images with like the way iPadOS does it. There are actually quite a few areas where Windows is a bit closer in some of those things. 👍🏻
I know this is a really long comment. But I guess that’s just some of my thoughts. But yeah, I do agree, maybe the desktop-first vs iPad-first delineation is part of this divide in perspective on this. 🙂👍🏻
