Google just announced that they upgrade their mobile search landing page, improved their Igoogle page and a added a new search-plugin.

I am not really surprised by that. The mobile web and especially the mobile search work completely different and with the growth of the mobile web, Google must be afraid of loosing market share.
They will keep on pushing in the mobile space as hard as they can.
