I haven't tried the new Netscape version yet but Firefox is super.
You must keep IE however as it is part of your windows system and trying to remove it will cause havok in your operating system. Additionally, IE is the only way to get Windows Updates.
Bottom line is you can have as many browsers as you want and can even use more than one at a time if your computer has the capacity to do so.
