Well Microsoft now has IE 7 beta 2 available for download. I have downloaded it and notice right away that tabbed browsing is available among other security features. I won't go into them. Here is the URL so you can look for yourself.
www.microsoft.com/windows/ie/default.mspxThere are things that I don't know how to do such as copy and paste yet.
Beware
Hah!! Microsoft finally did add tabbed browsing to it's IE product. I remember when people were compaining that IE should have tabbed browsing much like Firefox or Opera. Microsoft's reaction was negative towards the idea. Guess they finally had to give in.
