That's exactly what I mean. IE6 < IE7 < Firefox/Opera/Safari. And I'm a web developer myself, which is why I'm happy about IE7. I'm not gonna use it. But I'll enjoy people using it instead of IE6, that's for sure.
But a hell of a lot of people wont use it, it is only supported on XP SP2 and above, there are waaaay too many people running on a Windows OS that is not XP or Vista and are still using 6.
For this reason, there's no way in hell I am happy about the release of IE7, because people will start trying to write web pages for it, which will break in 6, alienating too many people.
This is Microsoft's fault, if they had just let people using pre-XP use IE7, there wouldn't be a problem.
