It is for most people. I have it on one of my units and it's OK. Still seems to have some bugs that need to be fixed. It won't download some of the games that I beta-test, so I use the other unit with 7 on it. Some people love it. I'm 50/50 with it. But soon, we will have no choice. I would wait until you have to if you're comfortable with your present OS. If you're running 8.1 then I would upgrade for sure.
I've been using it for quite a few months now and find it a vast improvement over Win8.1. Very happy with it.
i've heard a lot of bad things about it (most of the complains are about the wifi connection), i've tried it and i personally don't like it.
Just like Skunky said, I've heard a lot of bad things about it, I've also heard many stories of people getting hacked through. I wouldn't, but it's your choice. :)
I've been using it since its first release. Very happy with it. It has a couple of little wrinkles (eg "Windows wants you to sign in again" which it really doesn't) but I just ignore those and carry on regardless.
I don't think there are any real problems and have had a few major updates from Microsoft since installation, so they're working to improve it.
The instructions said "Install Windows 8 or better" - So I installed Linux.
windows 8 is ugly 100% I say change to 10.1 PS ive used both. And you CAN go back from windows 10, over to 8 again too.
