So yeah, I installed the IE7 beta on an alternate copy of Windows, since I didn't want to muck up my main machine, and after messing around with it for like 30 seconds, I was glad I did . . ! The interface is horrible. I know it's still beta and all, but this is probably pretty close to how the final will be. From all I can tell, they're just introducing features that other browsers already have. I'll post more things if I find anything particularly interesting.
