I use a combination of IE and Chrome on my desktop. I prefer IE overall, but I exclusively use IE on my Surface, reason being it offers the best battery life and works very well with touch.
The one thing stopping me from exclusively using IE on my desktop is the lack of a Session Manager or equivalent, because when IE loses my tabs it really annoys me - whereas in Chrome, I can open Session Manager and restore them.
If you guys know of something like Session Manager for IE, please do let me know.
