The IE7 BETA is available but I'm not sure whether I like it as much as IE6. It is good as it allows you more room on the screen for browsing but you can't easily move the various buttons and toolbar sections about e.g. the 'File', 'Edit' etc sections cannot be moved to the top etc. Also, 'Cleartype' is set by default and I don't know if you can turn it off. It doesn't change the whole system, just IE. I do like the tabbed browsing, however, that other browsers have.
Here are some pictures from the default package with no mods.
