I use EI7 because its professional, and the interface is fabulous. It's the exact same as firefox and i dont feel like having 2 browsers and more space taken up. I used to use firefox and loved it, but once EI7 came out i decided to switch back. All your folders (My Computer, My Documents) are basically considered being in IE. The browser is at the top of the folder =/. It's a bunch of stupid confusion to have 2 browsers...
