What more appropriate timing than the first few days following Black Friday (ah, weekend) to unveil the next @Work Android Collectible: Logistics / Mail / Delivery / Messenger. All that sales-crazed ordering means massive movement of goods from warehouses to your doorstep. Amazon, FedEx, and UPS trucks are everywhere in my San Diego neighborhood, this week.
Look both ways before crossing streets; the drivers rush from address to address. Do be polite and get out of the way, when the delivery dude or dame appears on sidewalk or stairs carrying a stack of boxes.
