I am starting to play with it, but for e-commerce design teams you might want to get an early start with IE Version 7 B2. At first blush looks like they copied the tabbed browsing luxury of Firefox. It also includes consolidated menu items, smaller icons, with an overall decrease in toolbar space. I note an emphasis on RSS feed integration. Not to mention a new feature to help with pesky phishing sites…not sure how they are going to fend off the “spear-phishing” sites but looks interesting.

ADDENDUM: While writing this entry and viewing the tour my IE 6.0 browser crashed.
