The Beta 2 version of Internet Explorer 8 is now available for free if anybody want to try it...http://www.microsoft.com/windows/internet-explorer/beta/default.aspx
Being a Beta version, it's still at an early stage of development, but there are some great new features in it.
For instance, don't you hate it when you accidentally close the entire browser? With IE8 you can reopen your last session, or last set of tabs so you don't lose where you were at.
And you can keep an eye on sites which frequently update by using Web Slices, which puts the part of a Web page you want to check in the Favourites Bar at the top of the screen. When the site is updated, the Slice is highlighted so you don't miss out.
