I've been working working working on a relatively complex user interface in JS at work lately (merging suspected duplicates from a CRM together, and specifying which fields from each duplicate contact is the "correct" field) . It involves a lot of DOM manipulation and user input/feedback. We make use of a jQuery in our app, and I was quite happy to see that although I develop in Chrome and Linux, the UI worked pretty much flawlessly on Firefox and Opera on Linux, and IE8 (and methinks 7, but can't remember) on Windows. We may be lucky in that we can ignore IE6 and earlier Firefox and Chrome, but my point is that something like jQuery does a damn fine job of abstracting away browser differences. May not be perfect, but better than we can afford to do. I say this because we probably all aware that we're stuck with JS in the browser for a while...
