Express Device(JS) is good to go.
isMobile(JS) correctly identifies Firefox for Android Tablet as an android tablet
JS Mobile Redirection Site is good.

They do some not-so-great tablet detection, but the point of that is to
prevent the tablet from being detected as Mobile (which their mobile
detection doesn't pick up our Fennec Tablet in the first place). So
we're good.
jQuery Mobile is good.
Mobile Agent doesnt do tablet detection.
Mooltools is OK
Stacking contexts LOL
Node User Agent Parse (JS) is OK
Platform.js fails just as hard on the rest :(
