I'm now running the latest beta of Internet Explorer 7 alongside Firefox, Opera, and (even) Amaya.
I've run up against many of IE flaws, so I'm glad to say that quite a few have been fixed in the latest release. I'm even limiting my special, conditional comments-enable css hacks for IE down to version 6 and earlier. Now, it's not perfect, the IE team still has a lot of work ahead of hit, but after years of stagnation it's nice to see some progress.
In addition, I'm actually pretty happy with the user interface. It's a nice departure from the past, and while I can tell there's still some "old IE" in there, I'm happy with the direction it's going.
I'm not dropping Firefox anytime soon, but I'm really glad to see some fresh change in the works at Microsoft. Now if we could only get some nice
application/xhtml+xml and image/svg+xml implementations out of Redmond...
