As a user of 8-inch Windows tablet alongside with bigger Surface Pro, I find that Windows 10 tablet experience is rather usable and okay, but far from great especially when we talking about tablets from 10-inch and below, especially the 8-inch I am using. So my experience is about on 8-inch which where the tablet experience on Windows 10 are truly tested.
Start screen
This is my first point of my tablet experience in Windows 10, all in all it is okay but bit unpleasant experience. It works okay for opening apps and showing Live Tiles, but usability is a big letdown from Windows 8.1. There are few sub-points I want to tell.
- All Apps - The experience is subpar, especially when coming from Windows 8.1 and even using Windows Phone/Mobile. Every time I want to access All Apps, I have to use my other hand and try to hit that All Apps button on the left side of the screen. This is inferior to the sliding gesture from Windows 8.1 (not the joke from Windows 8) and from Windows Phone/Mobile, which brings inconsistent experience if you have one. I don't know what gotten in their minds of not implementing slide gesture to open All Apps since the beginning and even now. It seriously need an ability to slide from right to left like on Windows Phone/Mobile to bring consistency across form-factors, usability and more natural interaction using touch and even for trackpad users. Seriously, I enjoyed having able to access All Apps using trackpad when using Start screen but we can't do that anymore even on Start menu when All Apps are hidden.
- Jumplist - This is where Windows 10 is better than Windows 8.X, the Jumplist feature first introduced with Windows 7 which is a wonderful underrated feature. The problem is when using on touch/tablet, the accessibility of Jumplist is more of an afterthought, especially when comparing or experience from iOS and Android similar feature. This needs to redesign the interaction on how to access additional Live Tile function using touch, and I propose that the current drag-and-drop mode should be replaced by Jumplist or better yet Interactive Live Tile when you tap-and-hold a Live Tile. Just move that Drag-and-Drop mode under a ellipsis sub-menu together with other non-task-related functions. Also it would be better if this gives a bit more polish with touch, such as slightly zoom the Live Tile when you open the menu like what Windows Phones used to do, this will give more focus and aligns to Fluent Design System principle Depth.
- Semantic Zoom - A forgotten feature which was actually great, now it only available on some Microsoft apps. Windows 8.1 got this feature when you can zoom-out to show the simplified overview of Live Tile groups to quickly jump to selected group. Though on All Apps list its still there when you only tap the letter header but there is no Pinch-to-Zoom gesture like it should be.
- Drag-and-drop - This is still a bit broken at times and unpolished experience. When you start dragging a Live Tile or apps from Apps List, it takes a split second then reappears and bit slow to use. The Windows Mobile/Phone is still better at this. Lastly there is still a bug that sometimes that Live Tile became invisible.
Task View/Task Switcher
On tablet mode, the experience in Task View is still unpolished and limited since Windows 10 first introduction.
- The lack of proper animation/motion is the most prominent afterthought in Windows 10 on tablet mode, it still only fades in and zooms from center, not from where it was actually located from the X-Y coordinates on the screen. Compared this on Windows Phone/Mobile for example, and even from desktop mode, this is unacceptable UX afterthought. The experience is disjoint and unnatural. Especially when you swipe from the left-edge, it makes a disconnect behaviour from the user's finger direction. For a modern OS like Windows 10 and from the previous UX implantation they did with AERO 3D Flip View, Windows Phone/Mobile Task Switcher, and Windows 8.X Task Switcher. What they did in Windows 10 isn't well-thought like its still an alpha state.
- I think the combination of ability to drag-and-peek action from Windows 8.X Task Switcher would be still great for Windows 10 when you slide your finger from the left-edge. It is more natural and easier when you want previous app to be snapped with your current app.
Windows Snap
This is something what I love about Windows on a tablet since 8, and its been improved with Snap Assist on Windows 10. Still as usual polish still needs a bit of work and limitation that hasn't been addressed still.
- Vertical Snap - Still a big limitation that hasn't been addressed since Windows 8.1. This allows the app to be snapped even on portrait orientation on tablet mode. Especially on tablet, having this is needed and highly desirable capability that Windows 10 still lacks. Not to mention the rather annoying sometimes that you can't even rotate the tablet when you already snapped something, since vertical snapping is not supported.
- Multiple horizontal snap - Windows 8.1 got this that we lost on Windows 10. It was great for large tablets such as Surface Pros to giant 20-inch tablets. Having more than 2 horizontal snaps that are resizable gives more freedom and flexibility to multitasking workflow on tablets. Microsoft is emphasizing productivity and yet they reduce the amount of Windows Snap in tablet mode starting Windows 10. Also, for large tablets and especially hybrids that are getting more common these days, having both vertical and horizontal (quadrant snap) similar on desktop mode would be desirable.
- Animations - This again, though not as bad on Task View animation in tablet mode, the animations on Windows Snap is bit disjoint, even on desktop mode (but the experience are bit better). They have to address this as part of Fluent Design System.
My People
A nice new feature that improves the communication and sharing experience in Windows 10. A feature that has been delayed for Creators Update and now they are finally releasing it with Fall Creators Update, the problem -- it is still half-baked, unpolished and seemingly not ready. On tablet mode, My People is even got worse implementation.
Since My People UI in Fall Creators Update is literally a window and not a flyout UI, it behaves like not like what we expect from their concept design as intended. This means on tablet mode, it acts just like another app, which consumes screen real-estate that tablets limited at, complicates the multitasking, and the experience isn't much different from opening an app. It should behaves like Facebook Chat Heads on smartphones and on small tablets. For big tablets that have more Taskbar space, then it should have pinned People like on desktop mode when allows.
Compact Overlay
I love this feature in Creators Update and use quite a lot on desktop use. On tablet? It is the opposite even though this capability makes more sense and useful for tablet than to the desktop. Compact Overlay behaves just like a dumb always-on-top tiny window, not an intelligent, responsive and touch-friendly floating mini-window.
- Dragging - Compact Overlay on tablet mode and even just using it with touch is tricky to use. You can only move it around with its invisible titlebar which auto-hides, instead of just able to drag around anywhere on the window as long as there isn't any button or UI controls. They have to address it by having the whole mini-widow to allow dragging when you hold-down for a second.
- Snapping on edges - Another missing thing on Compact Overlay is it doesn't automatically snap on edges of the screen. This makes managing another floating window tedious, especially for tablet use (even on desktop too). Typically they are just suited anywhere near the edge of the screen, but not really sticking to the edge. It doesn't have to be only stick near the edge, but when you drag near it, it should. There will be just an option to turn off this feature.
- Animation - Switching from full app window to Compact Overlay mode is always jarring and disconnected. That is because the lack of animation that show the motion where the content is transforming from and into. There is no visual feedback what is happening to the window, it just happens and up to the user where the window is. They really have to take note from what Apple did with Picture-in-Picture implementation which is really polished.
Microsoft Edge
This is the best browser so far for touch and tablet use in Windows 10, but not as great as what Metro IE did. Its still too "desktop" even on tablet mode. The always full-on UI chrome takes some space that is limited on tablets especially for 8-inches and below. It needs auto-hide behavior and even moving that addressbar at the bottom for better ergonomics for small tablets. Currently, Edge is acceptable for large tablets but not something from 10-inches and below.
Even then, there is a weird bug on Edge that still persist where sometimes the web page renders the desktop version with smaller scaling and you can't even interact with it, this is a bug mostly on mobile. There is another bug where context-menus are sometimes smaller than it should be.
On tablet, scaling are inconsistent between portrait and landscape, not great experience in regards to this which force me to always adjust the zoom level when switching between them. Microsoft Edge should smart enough about that and it should even automatically loads the mobile version if necessary on portrait mode.
Taskbar
I don't have too much problem using a Taskbar on tablet, even on small tablet but it still needs improvement.
- Pinned apps - We need pinned apps on Taskbar even on tablet mode, but it needs a button and seperate slide-out panel to show pinned apps. This will solved the issue when using it on portrait mode and remain Taskbar clean while not loosing the functionality.
- Taskbar overflow - Not necessarily just for tablet mode, but Taskbar needs better implemantation of overflow pinned apps. Currently when there is too many apps on the taskbar, it still literally use Windows 95 implementation to scroll through oveflow taskbar apps. Seriously, take a look how Android launchers done with their docks, just swipe it left and right. For mouse users, there will be just a big next and previous arrow buttons.
- Taskbar behaviour when switching full-screen apps - It need better behaviour when apps goes to full-screen such as sliding it down. It gives predictability of the UI behaviour when something changes on screen by using such animation, improving overall experience.
Gestures
- Action Center - The swipe/flick gesture is okay, but not as natural as when you can literally drag/slide Action Center to open and closing it, following your finger. It gives better feeling and feedback to the action of the user than just flicking finger that felt unpolished and artificial. It can also allows the user to peek through the Action Center contents, just like what we can do on Windows Phone/Mobile.
- Hamburger menu - Not necessarily for tablet mode only but still worth mentioning. This needs a standard sliding gesture like how Android hamburger menu as been implemented and few 3rd-party Windows apps that developers put more effort than what Microsoft does on Groove Music hamburger menu. Though on tablet this is tricky since sliding from left edge already reserved for opening Task View, so it doesn't really make difference. Though for apps that have exposed collapsed Hamburger menu like on News app for example, this is worth implementation. This thing should been addressed with Fluent Design System standardising UI components.
File Picker (and File Explorer)
This is the hardest part which is highly tied from Windows Explorer shell which is largely not touch-optimized and inconsistent UI design aesthetics from UWP and XAML Shell UI. Though they really have to at least make changes on File Picker even its not UWP to be touch-friendly with updated UI that is more consistent to usual UWP apps. This includes File Explorer. We need at least updated UI for these important areas of Windows 10, even its not UWP as we wait it to be fully mature and ready. We need at least a good stop-gap implementation before UWP File Explorer together with Cshell without a lose of feature.
Action Center on Lockscreen
Not necessarily just for tablet experience, but comparing it to Android and iOS, it is a big limitation not able to access notifications and other Action Center shortcuts while on Lockscreen. This affects the overall tablet experience in Windows 10 as users on tablet compared to desktop, ability to quickly view and interact to notifications without unlocking is common and make things easier for user.
Verdict
For now these are the things I come across when using Windows tablets especially for small ones. Overall its not that bad, but far from great either. Tablet experience in Windows 10 are highly an afterthought. I'm also afraid to say that iOS 11 finally caught-up to Windows 8.X tablet experience and even got some better stuff too, with only Windows 10 Snap Assist, and multiple horizontal snap from Windows 8.1 are missing. Pen capabilities on Windows 10 on Creators Update are also still great thing about it when you got a pen-enabled tablet, which is still better than iOS for the most part. If using Windows 10 on small tablets like 8-inch ones? Well, that's where tablet experience on Windows 10 falls apart.
