I loaded IE 7 RC yesterday. So far I had only 1 crash with it, but I like it a lot. I don't think it's going to stop me from using Firefox altogether. I do like the drag and drop tab reordering You get the opportunity to set them up the way you want and save it in the order you prefer, it kinda' reminds me of the way you can drag and drop slides in PowerPointe, but you can't drag and drop the panels around in Quick Tabs, which is a static view.[/b]
Yeah, IE 7 is a great advancement (and only three+ years late&#33, but Firefox can still do some tricks that IE just, you know, can't. I would probably still be using (and reccomending) Firefox as my primary browser if I hadn't grown addicted to the RSS support in IE 7.

It's weird how some people find IE more stable than Firefox, and some people find Firefox more stable than IE. Firefox tends to crash more often for me, but in all fairness, this is probably because I'm using more exotic, less-tested features like the Javascript debuggers etc.

I think the best thing about IE 7 is that they're going to actually keep developing, that is, start on IE 8 (or 7.5) the second IE 7 is out there, instead of just lumping us all with IE 7 and sitting on their butts for another six years. I think it's probably in response to Firefox's advancement. And they said competition was a bad thing.
