Google’s rate of Web Application development is nothing short of amazing. Not only do they break new ground (just consider the impact that Google Maps has had), but they also redefine and re-energize concepts that have gained very little market traction.
What I’m thinking about here is the concept of using Web applications offline. There have been all sorts of attempts to address this kind of functionality but none of them have had enough market traction to become mainstream. Google Gears is the product from Google Labs that could change that.
