I actually got burned by this recently. I used a some fairly high-end 
DOM stuff that was enabled after a a check for 
"document.getElementById". Unfortunately, Opera supports that, but 
hardly anything else usable in the DOM:
<http://www.opera.com/docs/specs/#javascript>

I've got around it by detecting Opera on the server-side, as I'm wary of 
checking for various DOM items (document.getElementById, 
document.createElement, document.styleSheets, document.getAttribute, etc.).

Cheers,
