I love IE9! It has been my default browser since the RC (I was using Chrome during the beta).
The new tabs page (about:Tabs) displays the most popular sites visited:
And now my web sites are just a click away!
Not surprisingly, this is my home page.
To set about:Tabs as your home page:
1) Open a new tab
2) Go to Tools –> Internet Options
3) Under General tab | Home Page section, click on User current
But I browse a lot of web sites daily and that 10 web sites/2 row limit is just too little for me! I wanted more sites to be displayed in my new tab (about:Tabs) page.
Thanks to Eric, there is indeed a registry hack to increase the number of rows in about:Tabs page!
IE9 team, please add this in the Options dialog box
