Cloud links, control / remote wiping, 3G / 4G, sensors, battery life; none of these matter to someone who works in a cube. I don't know about other manufacturing or office facilities, but the majority of my computer users stay put most of the day. I'll freely grant these advantages to other users, but I still question how large a percentage of computer-using workers require mobility.

Also, moving to cloud apps imply the company has assets to convert existing client-based apps to web-based ones, or that there's ROI in doing so.
