So, I deleted the comment where I applaud IE yet describe the extensions you just rewrote in almost parody (edit: misread Firefox on my mobile device as IE. Good point! I love Firefox too for these reasons!). But, my point is that the metro IE doesn't have extensions. Chrome does (the metro edition) because last time I checked it's just a frozen implementation of the desktop browser but full screen. Lack of extensions is the weak point for me for any browser. And, the metro IE and better scaling overall are the only compelling benefits I see to IE. So, I usually opt for Chrome (edit: or even firefox! :) )
