you mean its based on openWebKit, which Chrome and Safari use as well (I hate giving Apple credit for things they don't deserve- Safari is currently just an interface they designed for the open-source web kit designed for linux. They weren't even the first!).
Its the only openWebKit browser for Windows Mobile, and does some cool stuff.
funny that you can use it for GTalk... isn't there a native Gtalk client in the works? Or something using a SIP app like SJphone to plug into it? Gizmo project? These terms ring bells, but I haven't actually put them all together yet.
