OK, this is a neat way of giving your staff secure access to cloud services. The Dell Wyse Cloud Connect is a dongle you can plug into the HDMI or MHL port on any available display to connect to existing workplace services.
This isn't a perfect solution for portability, since you'll still need to have a keyboard and mouse to work through your documents. However, it's a neat extension of the existing notion of media centre dongles into the work environment, and easier to manage than a smartphone. Dell is selling the device for $187 a pop.
