I felt very suspicious about the whole affair to be honest. Microsoft giving me an OS upgrade for free? Yea, that doesn't sound suspicious at all! Turns out I was wright to be suspicious, and will stick with my old version of Windows until they decide to behave. The UI in 10 does look nice, but not at the cost of feeling like my OS will be farming my information. Maybe, hopefully, finally, one day - this will encourage people to invest in and explore ways to improve the Ux of alternative operating systems.
