Webkit on Mobiles (21st December 2009)
QuirksMode reports There is no Webkit on Mobile.
It seems mobile vendors take different versions of Webkit, then break/disable/remove advanced and experimental features. (Stuff from CSS3, HTML5, ES3 and hybrid features being drafted at W3C such as querySelectorAll().)
Ironically, this actually means there is lots of Webkit on mobile. It's just that they differ at supporting advanced and experimental features.
This might mean we should test Webkit-based browsers separately. Or it might mean they all support about the same amount of “baseline” technologies, so it won’t affect the way standards-compliant websites test mobile compatibility.
