How about Nokia World? This year it's combined with the Nokia Developer Summit which has been a separate event before. They've announced many devices/services in other mobile conferences too.

Can't remember Engadget etc. liveblogging many of those though, but who can we blame?

There I kind of agree, OPK & Vanjoki sure pale in comparison with Jobs and Ballmer. But I personally find those Apple keynotes pretty repulsive to watch.
