I recently took the ESRI course for the JavaScript API, but they didn't mention that apps developed on 3.3 and before wouldn't be compatible on IE10. It just sunk in that this could be an issue while reading the documentation. Anyone have any ideas about compatibility? I seriously hope that the course I took (and work i'm doing) wasn't for something that would basically be useless next year.
So far, I have not run into any issues with IE10 on Win8. Not to say that some things may not work. I think that section should probably be updated unless the API team hasn't run through all their testing in IE10.
But I don't think you should have any issues moving forward.
