I absolutely love questions that can be answered in about five seconds of research: http://www.apple.com/itunes/charts/paid-apps/ http://www.apple.com/itunes/charts/paid-apps/ Most of the games I would argue the value lies in the mobile software, and even for cloud-powered games there's none where the client is valueless. There's also a bunch of fitness apps, photo editing -- one of the top five is an alarm clock! Lots of apps are "financially successful" without just being a shim in front of a cloud server.
