I've showed some of these sites to a client as we have a Web app in the wild and I want to avoid the inevitable IE6 support calls. He is reluctant to use anything I've shown him so far since the language in the copy is always a little too pointed. He's afraid that users will get scared off, and he's probably right.

I think the default wording should use kid gloves, something like "To fully take advantage of this website, please upgrade your browser". Or maybe "This website uses advanced features that your browser does not support because it is out-of-date".

Has anyone done any A/B testing?

Good point. I'm working on a new copy. Will update it soon!
