I'm not really a Windows user (Debian with Cinnamon). I tried to use Windows 8 for a little while. I liked the ambition in trying to unify a mobile UI and Desktop UI, but it really just felt jarring switching back and forth. Does Windows 10 do anything to make this a bit more seamless or clean?
It's nothing revolutionary but they have tidied a few things up. The main changes that make the transitions less jarring are: 1. If the computer uses a keyboard and mouse (rather than a touchscreen) it will default to desktop mode. 2. In desktop mode, the start button brings up a menu, not the full screen Start thing as in Windows 8. 3. In desktop mode, the "Modern" applications can now be opened in a window instead of full screen. This is my experience from testing it in a VM on a desktop PC. Tablets will do something that looks more like Windows 8, and I'm not sure about touchscreen laptops.
Same. No idea how it works with tablets or convertibles. Desktop works fine though, and you can add/remove/rearrange the tiles in the start menu.
