I do and I don't wanna upgrade. It'll be interesting to see if any issues come up

I originally planned to wait for a few months to make sure it is bug free, but I have since changed my mind. I am upgrading day one now!

Nope. Windows 95 forever bitches!!

The final build takes less than 10 seconds to boot on my retina macbook! Earlier builds and windows 8 took about two minutes.

I'll probably upgrade as soon as all issues are gone.

Is edge a mandatory install?

Microsoft Edge is the new Internet Explorer, so yeah, it's included in the OS. Having tried it, it's actually a decently competent browser. It just needs addon support, which I guess is coming, and it could easily be on par with Firefox and Chrome.

But do they let you remove it?

Considering IE wasn't removable, I'm pretty sure Edge is going to be the same way. I didn't try to remove it, but I also don't see why Microsoft would let people remove it.

It was though.
