I'm liking it, I mainly use it in tablet mode. I like how when desktop apps are opened they are automatically opened full screen, and rarely as a window. It just makes the whole tablet mode seem more seamless. I'm enjoying Edge. Only having two metro options for web browsers previously was annoying, and since Internet Explorer did not display it's tabs at all times i opted to use the ghastly Chrome. Edge offers visual tabs which makes it an easy choice for me. It's not perfect, but it's better than Chrome.
I have seen some bugs. For example input areas in desktop apps do not bring up the virtual keyboard when tapped.
In many other apps, the virtual keyboard comes up as usual, but tapping off the keyboard does not make it withdraw, and i have to fling it down manually. That may be intentional but my habits make me not like it.
Another one that's very annoying is when i go to take a note in OneNote or draw in Fresh Paint, i rest my hand on the device and the god damn calender is triggered.
