I use it primarily on the desktop side of my Surface Pro but I love it. I've stopped using Chrome altogether.
I still have one issue where if I have 2 IE browsers open (not tabs, individual browsers) and I have one on my Surface screen and the other on my external monitor, it will constantly change the zoom size of IE my Surface screen. I have it set to 125% but I will go over to the external monitor, work there, then come back to the Surface screen and it will resize to 188%. I'll fix it back to 125% and when I come back it will be at 88%. Drives me nuts, and I'm sure it's a me thing, but can't figure out how to keep them the same...for full disclosure, this may have something to do with a specific work related website I have to log into to do some work. It doesn't seem to happen when I'm in anything else, or at least nearly as much.
Otherwise, I have never understood the much maligned IE experience, short of a very vocal few who want to be able to add a dozen extensions and widgets and such, and IE just clamps down on that. If that's the complaint, not sure I'm getting it.
