What I like the most about modern OS usability: 1. Autoplaying videos: you open a news site to read a text article about gold prices, and it starts playing some video about soccer or Putin in the corner. 2. Auto-updates, anti-viruses, auto-backups, indexing, garbage collection, cache flushing, runtime optimization/pre-compilation, and all that wonderful stuff happening in background, when you're trying to play a video game or do the work in Photoshop. 3. Myriad of ways to configure your OS. In Windows 10 we already have setting, control panel, regedit, msconfig, services.msc, and a lot more. Linux even manages to beat Windows 10 on that. 4. Basic functionality implemented in Python or Visual Basic, so a menu takes several seconds to pop-up in on a high end machines, while large data sets can easily eat up several gigabytes of memory, like the case with Linux package manager written in Python, which crashes with out of memory, when there are too many packages.
