Safari and IE 7, separated at birth?

Microsoft just showed off some features of their long awaited browser, IE 7, at Gnomedex (which we're blogging). IE 7 is supporting RSS in a big way, and is using that fashionable metal interface all the ladies love.

While I was looking at the video I couldn't help but have a sense of deja vu, but I couldn't place why. Then it hit me, but I think I'll let this picture do all the talking for me:

The browser above is IE 7 (using a beta, non-finalized UI), and below is Safari RSS.

I rest my case, your honor.
