Its been over a month now since Internet Explorer 8 was released on March 19th. I have been busy lately but I finally got round to installing IE8. I have to say I was impressed, it works well and is very responsive. I would have to say IE has caught up with FireFox in terms of all the features I like in a browser. I spent quite a bit of time developing websites so for me best of all is the built in developer tools and JavaScript debugger. I like FireFox and especially FireBug until now there was no equal when it came to debugging your javascript and CSS problems, but I think the IE8 developer tools make debugging a breeze and it is actually better and easier to use than the JavaScript debugger built into FireBug.
There is plenty of discusion on the web over IE8, just check out the blog at TechCruch certainly some keen FireFox users commenting there.
