Actually, Edge is improving quite a bit!
It's functionality, (on Desktops anyway), as far as mouse/keyboard focus, and the like, is where it sucks.
I'm looking forward to the new version, I like Edge, OK there have been problems on this machine using it and I've had freezes and such but I keep going back to it after using Chrome and Firefox every so often. I had problems with IE on here as well but instead of sniping about it or having a go at others on their choice of browser I'll just carry on, if one doesn't work change to another for a while, there's always the chance it's my fault so I'll learn from my mistakes and move on.
Nothing is ever perfect and I wouldn't want it to be how would we learn and improve things if they were perfect to start with, it'd be very boring if they were.
I have been using Edge as my daily browser when I'm on my Insider build and Pale Moon when I'm using the RTM build. I can truthfully say that even with the improvements to Edge I still prefer Pale Moon over Edge.
If Edge ever gets up to the usability of Firefox, and can use similar extensions then I will consider using it as my main browser, simply because I like a clean lean system and want as few browsers installed as possible.
Been using Edge almost exclusively since upgrading to 10. Sung its praises to one and all, but after the last update I've been having problems with it freezing. A lot. The "last update" thing is just an approximation but around that time anyway. I still use it about half the time as it is a decent browser, but I don't even try MSN anymore while using it. Cannot finish even a 1 page article without freezing. When I switch to either F.F. , Avant, I.E., or even Opera I have no such problems. Yes I have 5 browsers these days .
