Getting a major OS update is almost like buying a new phone - you get a host of new features, (hopefully) faster software and occasionally a complete overhaul of the UI. It's actually better than a new phone, it's free! Yep, phones never had the PC model where a new version of the OS is something you buy. That's good on the surface, but there's a flip side. You can update a 10-year old PC to Windows 10 without waiting on its manufacturer. You probably shouldn't, but you can. With phones, you pay nothing for updates and sometimes you get your money's worth. That's not true for all...
