Well, I upgraded my PC from 7 to 10. So what do I think so far? I don't hate it.
It's just that I will have to get used to it, which may not take long time.
And of course so did I have to eradicate Microsoft's own web browser. because I use Firefox. (In before Google Chrome users telling me that Chrome is better than Firefox.)
I also hope it's true that there will be no other versions of Windows after 10, and that they're focusing on making patches and upgrades for it.
I don't think I need to remind you all, but I still got my 50% christmas sale (hey, might as well call it that since November is almost over).
