Whilst I really don't enjoy having to make websites compatible with IE (mainly 8 and below), I'm really glad they're sticking with IE as a browser. WebKit seems to have a monopoly on phones and so many mobile sites (and tutorials) don't think about other browsers.
I'd prefer more phones to ship with Gecko (Firefox), like my Nokia N900 but anything non-WebKit adds to the diversity.
Edit: I don't really have anything against WebKit and understand that it makes sense for mobiles as it's easily embedable but the fact that it has a monopoly in the mobile space really gets to me!
