Seriously! After using MUI IE, using other browsers is a downer. I find the MUI version of IE to be slick and smooth. I liked it on my Surface 2 which I used to use earlier, but on the SP3, it is simply brilliant! I wish all browsers were like this.
I would flag a couple of things as possible enhancements/ improvements. For example, to use tracking lists one still has to do this via the desktop version of IE. One way around this would be to have something like a MUI IE Control Center where such stuff can be enabled/ disabled. One other thing I would like to see is the ability to install curated plug-ins (especially function-specific plug-ins that corporates require their employees to use). As an academic, it would be excellent, for example, if some reference software (like Mendeley etc.) could have plug-ins. Again, installing it via the aforementioned Control Center would be the way to go. Another thing would be to use the compatibility functions via such a Control Center. This way, the desktop version of IE could plausibly disappear!
