Thought I'd open a thread for this. Microsoft just announced that Windows 10 will be free for Windows 8 and Windows 7 users, as well as Windows Phone 8.1 users for the first year of availability. They're also framing W10 as a service rather than a product. I'm sure I'll be upgrading, but I don't really know what the benefit will be (yet) other than not having to deal with the Modern interface. Better functionality across devices sounds cool, except I don't have any other MS devices besides my work and home PCs.
