Edge is really fast but is missing some of the stupidly obvious stuff. Like clicking a folder in the Favourites Bar then right-clicking one of the URLs. Nothing happens. No options to open in a new tab, open in a new window, open in an InPrivate window. Nothing. And if you're on a Windows tablet, such as my Surface Pro 3, you long-press some text but there's no Copy, Cut, Paste, etc, just Select All. I only found out by trial and error that you can tap a word and it will be highlighted, then you can drag the handles to select more. Not that intuitive, and not the way it's usually done.
But still I find myself using as my default browser on my tablets, because it's so light and fast.
