All apps (especially sharing and authoring apps) will be location enabled in the future. This is just the start.
I agree with people who described this as a “watershed event“ in making location-enabled applications available to American (and Canadian) businesses at prices they can afford. If your business involves sending people to customer locations, whether on service calls, deliveries, or “when news happens“ this is technology you can use. Maybe not immediately, as we are still a bit on the bleeding edge, but now is the time to get this on your radar and plan for 2005 and beyond.
