IE is like that driver disc you get with any new graphics card. It comes with it, but you throw it away because you can download something better.
Yeah,.......IE "stays in the box" at my house. I have a flash drive with Firefox on it with the default page set to www.ninite.com.
I load it on a clean install of Windows and go to Ninite to D/L all of the free programs that I like. I try not to use IE at all.
IE's awful versioning system, and lack of built in PDF/Flash support and cloud user account features makes it not even a choice in my opinion compared to Chrome.
