CSS Device Adaptation (uncompleted)

OK, I can confirm desktop IE and Android Opera Mobile, but it's difficult to me to test all the browsers and its versions myself.
Please help!

...I think none of those browsers support it yet, however.

I did the test for IE and Android Opera, and maybe some other mobile browsers I forgot, but I got bored and stopped to test, and now I think I should ask some help rather than just doing nothing.
