I got used to IE Metro back when I was working on ThinkPad Yoga, now I'm using it exclusively for touch based work and when I need to work a lot with mouse and keyboard I switch either to desktop IE or Firefox. Lately, I use IE desktop more, compared to Firefox- ad blocking works well enough in IE and it feels lighter and more responsive to Firefox.
I left Chrome few months back for good, it's constantly getting slower and heavier on resources and Google's need to bug me with unwanted new functions like overlay for windows and stupid tray notifications that each new build pesters me with finally made me hate this product.
