No offense to IE lovers but..... I don't.

I don't like IE at all, and fully support the people who want to have M$ give the option of Browsers at install.

But thats just me. As to what I think it SHOULD have, M$ should take a leaf out of Google's book. Each tab (this goes for Mozilla too) should be its own process, eliminating crashing all tabs.
Security should also be SO MUCH BETTER. It is the LEAST secure browser and I don't use it for that reason (along with clutter).
I think it should have MUCH less clutter when you first use it, and allow you to add it all in a very SIMPLE way. People are stupid, so keep it easy.

Any other ideas?
